Description

Waveform reformation power supply

The present invention relates to a kind of electric power conversion apparatus, specifically, is the integrated drive generator that a kind of employing Waveform reformation power supply (WRT) constitutes.

For generating various specific waveforms, or transform to another kind of power waveform from a kind of power waveform, or become the stable power waveform from unsettled power waveform, prior art adopts signal generator, convertor (becoming the motor that exchanges as direct current), transformer (changing the electrical equipment that exchanges amplitude), amplifier (voltage or current amplitude amplify), inverter (direct current becomes direct current or direct current becomes interchange), stabilizer (burning voltage, electric current, frequency etc.) and various circuit, all above these apparatuss all exist such-and-such shortcoming more or less, low as electric energy conversion usefulness, the waveform distortion height, use face is narrow, and control performance is poor.

Fig. 1 is periodic voltage waveform arbitrarily, makes the waveform in its one-period be divided into from t ₀To t _nIndividual time slice then corresponding to each constantly, just has from V ₀To V _nIndividual magnitude of voltage.If n is enough big, this corresponding voltage value in this period can be thought constant, if existing in addition from V ₀To V _nThe alternative words of voltage source of individual (no more than n kind) different value, just can obtain the electric power output of this waveform ideally by the desired program of waveform these voltage sources of gating successively with electronic switch, the waveform synthetic method that Here it is is studying is at present seen UK Patent Application GB2015-834A wave-form synthesizer (WAVEFORMSYNTHESIZER).In order to obtain waveform preferably, just need a large amount of voltage cell with the waveform synthetic method, and each voltage cell all must be furnished with a gating switch and a null value diode, thereby make apparatus structure huge, cost up is so the waveform synthetic method has been subjected to certain restriction in practicality.

Purpose of the present invention reduces the number of voltage cell just at the defective of above equipment, makes integrated drive generator simple in structure, is easy to carry out the manual operation combination or adopts digital control technology, Computer Control Technology to implement Automatic Combined.

The present invention has been achieved in that some voltage cell, be combined into needed integrated drive generator for gating, every voltage cell has a corresponding numerical value gating switch, the numerical value gating switch is controlled by the controller, controller provides output waveform data, it has decoder, and this decoder connects with circuit mutually with the numerical value selector switch.Set voltage cell is that m advances the numeral system power supply, total n(m-1) only, press n position m system numeral system rule and select to arrange that the magnitude of voltage of the voltage cell on the capable b column position of a is bm ^A-1Individual unit voltage; , and then in parallel in the like poles of each voltage cell on the same line number position with a public null value diode reverse with in parallel in the same way after separately numerical value gating switch is connected in series.Two end points after the public null value diode of the different numerical digits of each row is connected in series in turn by figure place are connected with the input of commutation bridge.The commutation bridge is to be made of two pairs of commutation switches, and it is used for changing the output polarity of integrated drive generator, and the output and the filter of commutation bridge link with circuit.

First application in the WRT principle is numeral system power supply and voltage synthesizer, reaches the direct current integrated drive generator that is made of the voltage synthesizer.

The numeral microelectric technique development enlightenment we, if replace being used in a large amount of voltage sources in the waveform synthetic method with quantity numeral system voltage source seldom, power supply with the numeral system voltage that is called unit (ELE-MENTS) among the present invention (DIGITAL VOLTAGES) is arranged connection by the numeral system rule, be called voltage synthesizer (VOLTAGE SYHTHE-SIZER, abbreviation VS) power section is reassembled into independent one by one voltage source earlier to replace a large amount of voltage sources in the waveform synthetic method, numeral system power section in the synthetic step by step more complete waveform, Here it is the present invention-WRT.

Fig. 2 is four quarternary VS, from E ₁₁-E ₄₃Voltage relationship between 12 unit (1-12) should meet four quarternary numeral system rules, and seeing Table 1., to establish unit voltage (UNIT) be 1V, then E ₁₁=1V, E ₂₂=8V, E ₃₃=48V .... as unit voltage is aV, then E ₁₁=aV ... E ₄₃Numeral system among the=192aV.VS and figure place can be selected arbitrarily, the unit of peak can increase and decrease arbitrarily, even each unit can arrange that also its purpose is nothing but to form needed maximum magnitude of voltage in the application with minimum unit according to specific application need not according to the numeral system rule of strictness.But the magnitude of voltage that can form one group of equal difference numerical value in general with the numeral system power supply with minimum unit, and it is very convenient to control, encode.12 voltage cell (1-12) are arranged, 4 null value diode D (33) ₁₁-D ₄₁(29-33) with 16 electronic switch S ₁₁-S ₅₄(13-28).It connects rule: three power cathodes of the unit (1-3) in same delegation (numerical digit) are connected with the anode of (29), positive pole (1-3) respectively with switch S ₁₁-S ₁₃(13-16) the common negative terminal with (29) in series connection back links, and forms the lowest order of numeral system power supply.By same attached method, (4-6), second (being high one) of (16-18) and (30) composition numeral system power supply; (7-9), the 3rd of (19-21), (31) composition numeral system power supply; (10-12), the 4th (being highest order) of numeral system power supply formed in (22-24), (32).The anode (34 ') of negative terminal of first diode (34) and the 4th diode becomes AA ' and receives by S ₅₁-S ₅₄(25-28) four commutation bridges (POLARITY BRIDGE) that switch is formed.Always (34) for just, (34 ') for negative from voltage that the unit synthesized, but through behind the commutation bridge, and as (25) and (28) conducting simultaneously, then the B end is for just, and B ' holds to negative, and as (26) and (27) conducting simultaneously, then to hold be to bear to B, and B ' holds to just.So it is requisite that the unit that the commutation bridge is same direction to be connected produces the interchange output institute of opposed polarity.

If four quaternary power supplys of Fig. 2 are expanded as n position m system power supply, just become the structure of Fig. 3, table 2 is the voltage relationship between the unit in the m system power supply of n position.

Fig. 4 and table 3 are with the structure of the voltage synthesizer (33 ') of eight-digit binary number numeral system power supply formation and the voltage multiplying power table of unit.

(33) each electronic switch (13-24) in is called the numerical value gating switch, (25-28) is called reversing switch.The break-make control principle of these switches is:

1. switch as (13-28) is gating not, though or gating arranged, (25-28) gating not, V (13-24) _{BB '}=0V;

With three switches in the delegation at synchronization, a switching gate can only be arranged at most.As synchronization in (13-15) can be gating not, gating wherein, but cannot be more than two or two gating simultaneously;

3. the gating of the switch in different each row is irrelevant, for example the not gating of (13-15) this delegation's switch or any gating and (16-18) this delegation or (22-24) this delegation switch whether gating is without any restriction, vice versa;

4. in (25-28) four reversing switches, (25) and (28) are called the forward switch, and (26) and (27) are called the negative sense switch, and switch of the same name is gating simultaneously, and non-switch of the same name is gating simultaneously anything but; V _{AA '}≠ 0 o'clock, the negative sense switch must cut out before the forward switching gate, and gating is V as a result _{BB '}＞0, (33) output positive voltage; Otherwise the forward switch must cut out before the negative sense switching gate, and gating is V as a result _{BB '}＜0, (33) output negative voltage.

Layout and switch control principle according to Fig. 2, the conduction voltage drop of ignoring switch and diode, suppose that unit voltage is 1V, then just can be only with the numeral system power supply of 12 unit, 4 null value diodes and 16 electronic switches, produce 0-± 255V through suitable gating, add up to 511 kinds integer value voltage.For example, make V _{BB '}=64V then answers gating switch (22), (25) and (28), and at this moment, the anode of (10)=64 arrives the B end through switch (22), diode (31,30 and 29) and switch (25), and B ' end then arrives the negative terminal of (10) through switch (28).Similarly, connect load as output (36), make in the load to obtain-206V voltage (ignoring the filter pressure drop), then should make switch (14), (18), (24), (26), (27) gating, the simplification circuit after the conducting as shown in Figure 5.Dotted arrow is the direction of current flowing among the figure.(29), (30), (32) are owing to instead ending partially, the null value diode of delegation unit that does not have switching gate is as (31) forward conduction always.And the voltage of different rows unit, series aiding connection addition always.As seen from Figure 5, the voltage V in load this moment _oFor:

V _o＝-（2+12+0+192）＝-206V

Be not difficult to find out, the eight-digit binary number numeral system power supply of Fig. 4 also has the fan-out capability identical with Fig. 2, but unit number reduces to 8 from 12, the electronic switch number reduces to 12 by 16, number of diodes increases to 8 from 4, and economy is good than Fig. 2, when only considering switch, diode drop, the pressure drop of Fig. 4 circuit is bigger, and efficient is descended to some extent.

Unit in the numeral system power supply (1-12) can be the generating body of no electric power storage abilities such as solar cell, thermocouple, also can be storage battery, dry cell.Storage battery can be charged through multi winding transformer (37) and rectifier (38) by single-phase or polyphase ac electric energy.Storage battery also can by the energy storage capacitor of enough capacity (1 ', 2 ', 3 ' ...) replace, but the numerical value of institute's accumulating voltage should meet the numeral system rule on this moment electric capacity under normal condition.Like this, the numeral system power supply just can be supplied with by electrical network or other electric energy of economy.Fig. 6 is the numeral system power principle figure of Alternating Current Power Supply (the primary unit that only draws among the figure, other three roughly the same Therefore, omited).Identical n phase transformer (37), n commutating phase device (38) just can be formed n phase charger to storage battery or capacitor charging.Be to reduce the cost of transformer and energy storage capacitor, the elementary of transformer also can be powered by the higher interchange of frequency or by the midfrequent AC after the dc switch copped wave.

Electronic switch (13-28) can be transistor, field effect transistor, also can be controllable silicon or other electronic switch, when frequency is low in addition mechanical switch or relay contact switch can.If use bidirectional switch, can realize the purpose of the electric energy of load end to storage battery or capacitor charging feedback.

Filter (35) is to be filtering electronic switch strobe pulse frequency f s(90) ripple Shu Chu And reduce the middle and high frequency be defeated by load and disturb and establish, because fs is high more than the frequency of waveform output, and the waveform with WRT output can be very near required ideal waveform, so the present invention is very low to the requirement of filter, filter can be quite simple, and the energy loss on the filter just can significantly reduce.

The structure of applied voltage synthesizer VS, can use seldom plurality of units, obtain the direct voltage of the different magnitudes of voltage of tens times even thousands of times quantity, more since the efficient of VS than direct current stabilizer height, volume is very little, so be well suited for becoming a kind of new product-direct current integrated drive generator as Portable DC multipurpose power supply.

Fig. 7 is the direct current integrated drive generator line map with mechanical switch, its VS adopts the eight-digit binary number numeral system power supply synthesizer of Fig. 4, unit and null value diode are constant, but its numerical value gating switch (48-55) is replaced by 8 double-pole single-throw (D.P.S.T.) mechanical switchs (48 '-55 '), and 4 reversing switches (25-28) are by a dpdt double-pole double-throw (DPDT) mechanical switch S ₅₅(75) replace.The left-half of (48 '-55 ') plays gating unit, and whether right half part can be used for respectively connecting indicator light (65-72) so that indicate the unit on this to connect.(65-72) can be common pilot bulb (with exchange or direct current supply can), also can be light-emitting diode (with magnitude of voltage suitable unit or other direct current supply), CC ' (73) is its feeder ear.Certainly replace indicator light better for purpose of power saving with the mechanical break-make indicating device on the switch.C ₁(74) be total filtering capacitor.Available dry cell in unit (40-47) or storage battery are formed, if make the unit with storage battery, can use multi winding transformer (37) and rectifier (38) to its charging.In the place that AC power is arranged, (39) can be by (37) and (38) power supply, and at this moment the unit can replace storage battery by cheap capacitor.For the voltage that makes each unit more stable, also can power with 3 phases or polyphase ac, as input AC being rectified into direct current earlier with switching regulator, this direct current frequency Jiao Liu And Zhong electronic switch is chopped into increases voltage stabilizing function in the inversion process, then not only the voltage regulation performance of device can improve, and volume, the cost of (37) and the capacitor used as the unit will greatly reduce, and portably use more convenient.Unit in this direct current integrated drive generator also can be replaced the part capacitor and be constituted the common power supply type of alternating current-direct current by storage battery, and promptly when Alternating Current Power Supply was arranged, direct current output was all by exchanging supply of electrical energy; And when no Alternating Current Power Supply, a certain or several VD can be by the one or more secondary battery unit power supplies in the device.This direct current integrated drive generator also has a very big advantage, exactly in the place that needs multi-channel DC to power simultaneously, can connect the all-in-one-piece unit with eight by the terminals at device rear portion and resolve into eight groups of independently unit, again with these unit on demand reconfiguration become mostly to be eight tunnel independent output voltage most, reach the purpose that multi-channel DC is powered simultaneously.

As seen from Figure 7, only use a transformer (37) and one group of rectifier (38, need 16 rectifying tubes), other adds 8 diodes, 9 capacitors, 9 mechanical switchs, 8 light emitting diode lamps, 18 binding posts (only drawing among the figure 2) and other a small amount of annex just can constitute such multipurpose DC power supply, and its characteristics are:

1. can obtain adding up to 511 kinds of equally distributed voltage ， And can export by mechanical switch immediately on demand;

2. can increase and decrease the voltage of 1 unit or several units arbitrarily, can change polarity of voltage and need not change wiring;

3. can make mostly to be most eight tunnel direct current multichannel easily into exports simultaneously;

4. can obtain maximum power output benefit, i.e. low-voltage, high-current output or high voltage-small current output;

5. easy to manufacture, cost is low;

6. power-efficient is very high, and power savings is obvious.

If the unit voltage in the numeral system power supply of Fig. 7 is 1V, ignore the conduction voltage drop of diode, this device just has 511 kinds of integer value voltages outputs from-255V-+255V.The unit voltage value is more little, and the difference between the adjacent output voltage values is just more little, regulates thin more.The figure place of numeral system power supply is many more, can be big more for the quantity of the magnitude of voltage of exporting, as binary numeration system power supply with Unit 16, just can obtain the even distribution direct current output of 131,071 kinds of different magnitudes of voltage, be 8 of unit number, more than 000 times, can obviously see the advantage of WRT in view of the above than waveform synthetic method.

Numeral system power supply with other systems also can replace (39), if but because misoperation, promptly closed simultaneously with the numerical value gating switch more than two or two on the numerical digit, the unit of so different voltage values causes the voltage short circuit with You Yu And connection, for preventing short circuit, just must increase interlocking.Fig. 8 prevents the interlock established with the unit short circuit on the numerical digit.Wherein a) figure is the switch interlock, it is characterized by, null value diode (29) moves on to right-hand member, except the switch on (29) unit farthest need not interlocked, on the coordination other all numerical value gating switches all need change into single-pole double-throw switch (SPDT) (as among the figure 14 ' and 15 '), when the gating switch on certain unit closes a floodgate, be connected on other the same bit location on A circuit far away, even its numerical value switch on also will be cut off automatically.B) figure is the diode interlock, it is characterized by, and except that the unit of maximum voltage value, other unit all should add the Series lock diode on the coordination, as the D among the figure ₆₉(76) and D ₇₀(77) be the diode that prevents short circuit between (1-3) three unit.Like this, when the switch connection of two unit was arranged on the coordination, the interlocking diode of being connected on the lower unit of voltage will be automatically by partially anti-, even switch connection but this unit, road still can not be connected, thereby prevented short circuit effectively, played the interlocking effect, other connection is identical with this connection.

Second application of WRT power supply is control signal decoder (CONTROL SIGNAL DECODER is called for short CSD, 84), sees Fig. 9.Voltage synthesizer (33) not only can be used as the direct current integrated drive generator, but also can produce various interchanges output.Obviously, if the electronic switch (13-28) in the gating (33) one by one according to certain rules continuously, its output just will produce certain voltage waveform.

(84) constitute by the ROM memory usually,, also can adopt EPROM or EEPROM for the ease of debugging and modification.If can accomplish does not cut off the power supply loses, and RAM also can use.(84) be the control signal memory device that is used for storing those switches in when should gating (33) of switch control information in (33)-promptly.Press the different of the content of store information and address, (84) can be divided into general controls signal decoder and dedicated control signal decoder.

(84) incoming coded signal (85) is received (d+1) bit address sign indicating number (86) as the address gating signal of ROM, its output control signal (88) is from (C+1) bit data position (87) output of ROM, and its data bits should be corresponding consistent with the switch number in (33).16 switches are for example arranged in (33), but wherein 4 reversing switches are two, two paired break-makes, two kinds of gating signals of needs are so (88) only 14 of need are just much of that.Because the switch one in (33) has 511 kinds of gating modes, so (84) should have 511 addresses at least, i.e. 9 binary addresses.Export thereby obtain a certain voltage corresponding to a certain switching gate mode each address.For (84) used on the binary voltage synthesizer of n position, its address adds up to 2 ^N+1-1, promptly need (n+1) individual address bit, data bit is (n+2).Voltage synthesizer for non-binary n position m system will have 2m according to table 2 ⁿ-1 magnitude of voltage, therefore (84) just have 2m ⁿ-1 address just can obtain the figure place of binary address according to this number of addresses, can be regarded as to such an extent that data bit should be n(m-1 simultaneously)+2.

For simplicity, the present invention only the output voltage values table of the symbol binary code establishment of employing table 4 be illustrated.If the encoded radio of output voltage is identical with the address code of (84), just can unite the encoded radio of the encoded radio of address and output voltage.When the input signal of such code signal (85) conduct (84) arrives its address bit (86), strobe pulse VCK(89) in case is 1, control signal in this address will start corresponding switch in (33) immediately, make (33) output and the voltage of (85) identical code value, Bian Zhi (84) just are called the general controls signal decoder in this way.Obviously, offset binary code or offset binary code or other inclined to one side coding mode can be used in the signal decoder of the present invention equally.For example, according to table 4, if will produce-the voltage output of 206V, can be earlier with-206 code signal 1CEH that are translated into 16 systems, can make the control signal of (33) generation-206V voltage leave the memory space that the address is 1CEH in advance in again.Then when this address of gating deposit the storage sky between And when (89) are 1, switch (26,27,24,18,14) conducting immediately, output can obtain-206V voltage.Obviously, the address value of general controls signal decoder is equivalent to a numerical value direction board, and the numerical value on the direction board is the output voltage values that can produce.

Automatically export the voltage waveform of certain amplitude and frequency if require (33), this just must be divided into n five equilibrium to this waveform by the time, again the pairing magnitude of voltage of each time Along ent is encoded, these codings are translated into control signal according to chronological order according to table 4, these control signals are deposited in (84) according to the order of sequence, (84) so just are called dedicated control signal decoder (84 '), as a means of difference.So the priority time sequencing that control signal is chosen in this address is represented in the address of (84 '), promptly always big than code value address, the address that code value is little is chosen earlier.The address value of dedicated control signal decoder is equivalent to a sequential direction board, and the time series of memory contents in this address is chosen in the numeric representation on the direction board, and the magnitude of voltage of (84 ') representative has nothing to do with number of addresses always by what memory contents determined.

Decoder is controlled by strobe pulse (89), and Figure 10 is its oscillogram, and Vck=1 represents gating, Vck=0 represents not gating, promptly at ton time internal gating (87), during toff (87) everybody be zero so that carry out address transition, ton should be much larger than toff.

The 3rd of WRT power supply is applied as usefulness (33) and (84 ') constitute the random waveform supply unit that can export the permanent width of cloth of constant frequency.

Figure 11 is the schematic diagram of structure of the present invention.14 tunnel control signals of (84 ') data bit are delivered to (33) after being amplified by driver (102) among the figure, and counter (100) is used for (84 ') are done to add 1 addressing, promptly is that OOOH → 1FFH visits all over one by one from the address, returns OOOH from 1FFH then, repeatedly circulation.Clock (101) is supplied with (84 ') required strobe pulse, also supplying with (100) count pulse carries out synchronously, also can provide synchronous switching pulse as needs to (102), (102) should be able to provide the drive signal of the switch open and close on time that make in (33), if use transistor switch, wish that then drive signal has the waveform identical with (89), if when using reverse-blocking tetrode thyristor, its drive signal should comprise the drive signal that drive signal that switch leaves and switch are closed.Introduce with Figure 11 device below and produce output voltage V=110V, the method for the sine wave of frequency F=50HZ.

Because (86) are 9, maximum 512 addresses can not surpass this number so produce sinusoidal wave pulse step number.If N=320 is by 360 °/N=1.125 ° (angle that each step is shared), then 320 moment point t ₀-t ₃₁₉Pairing 320 magnitudes of voltage can calculate V by formula _n=110

-3V。

Finding with each magnitude of voltage according to table 4 is the control signal of code value, and this control signal is filled out being designated as in memory contents one hurdle of decimal address with V following, sees Table 5.Content with table 5 deposits among the ROM again, and such ROM just is called the sinusoidal wave dedicated control signal decoder of 110V.

(100) are adjusted to the count range of 0-319, and promptly when counting the 320th pulse, (100) produce to overflow and return zero.

The pulse frequency of (101) is adjusted into fs=FN=50HZ * 320=16KHZ.

The unit voltage of (33) is decided to be 1V.

Because we have been amplitude that the sine wave of 156V is stored in every the control information of 1.125 ° functional value in (84 '), so when counter (100) adds 1 to 13FH from per step of address OOOH, being stored in 320 control signals in (84 ') takes out successively and delivers to (33), the sinewave output that (33) must be combined into an amplitude is 156V.(100) make address 13FH turn back to OOOH more at this moment, and then the waveform of second period just begins to have made up again, and this process constantly repeats, and just can produce the permanent width of cloth sine voltage output of lasting constant frequency.If electric road And does not require from sine wave certain and a bit brings into operation, then (100) can be provided with a device, instead then, (100) just a device must be set, usually the set device is replaced by zero setting device, at this moment the control signal of output waveform just should begin Bian Zhi And from required starting point and is placed on the ROM internal memory that the address is OOOH, compiles 13FH then successively.

Because in actual applications, (33) diode, switch element, circuit etc. always have certain voltage drop, each voltage cell also always has certain internal resistance pressure drop, also have the small loss of voltage on the filter, the loss of voltage that also has the switch down periods at last, the capital makes the each point magnitude of voltage on the actual waveform be lower than theoretical value, this just should revise the control code that is stored in (84 ') by debugging in advance, no matter such correction all is necessary and is suitable for for general controls signal decoder or dedicated control signal decoder.For example press table 4, control signal in the OC3H address should be 01100000000100, the output voltage theoretical value is 195V, if stagnation pressure is reduced to 2V when finding at nominal load in the reality debugging, then the control signal in this address should be modified to 01100000001001, revised signal can just increase the output of 2V than original signal, has compensated original output pressure drop.Just can pass through industrial production through debugging and the control signal revised, write in a large number in ROM, the debugging compensation technique and the industrial process of Here it is control signal decoder.

Same principle, sinusoidal waveform or the non-sinusoidal waveform dedicated control signal decoder of working out other amplitude replace original (84 ') can produce the sine wave or the output of non-sine periodic waveform of other amplitude.

As long as the appropriate element of selecting, well-designed and debugging, this device can produce the electric power output of the random waveform of the permanent width of cloth of various constant frequencies.

The 4th of the WRT power supply is applied as the supply unit that produces the output of frequency conversion luffing voltage waveform.

If the special-purpose CSD(84 ' with Figure 11) change general CSD(84 into), clock (101) changes adjustable pulse frequency clock (abbreviation adjustable clock 101 ') into, between (100) and (84), increase waveform coding memory (WAVEFORM CODE MEMORY again, WCM, 110), multiplier (111) and amplitude controller (AMPLITUDE CONTROLLER, be called for short AC, 112) three elements just can constitute a simple frequency conversion luffing power supply, see Figure 12.

Be understood that,, use the circuit of Figure 11 so, just can solve as long as will (101) change (101 ') into if only need change the frequency of power supply.Because after clock pulse frequency changes, to finish the time of 320 a steps cycle and will for example fs be brought up to 19.2KHZ by 16KHZ along with variation, the frequency of output AC will be brought up to 60HZ by 50HZ; When fs was dropped to 12.8KHZ, the frequency of output AC was reduced to 40HZ.When changing frequency, as long as the toff of strobe pulse＜＜ton, the amplitude of output AC can remain unchanged (the amplitude size is mainly determined by the control signal sign indicating number) so.So in Figure 12, the frequency conversion problem of output waveform can solve by above-mentioned modification.

Realize luffing output, just must change control signal in advance, and control signal and coding different in kind, in case formulating the back just can't revise, more difficultly carry out logical operation with it, just control signal and waveform coding should be separated for this reason, promptly still adopt general controls signal decoder (84), and leave the waveform signal coding in another ROM-(110) in, this coding also press symbol binary system establishment, also has 320 to go on foot, identical in address and the table 5, but content changes number into by control code, this number is carried out multiplying, and the waveform coding that multiplier (111) is sent (110) here is multiplied by a multiple, is equivalent to the code value of waveform be amplified or dwindle, can reach the purpose that changes waveforms amplitude, contract, the multiple of putting is imported by (112).As will become 120V to the amplitude of sine wave by 110V the time, so earlier by (112) to (111) input multiplier 120/110

1.091, so original each signal code value all will multiply by same multiple, be-12 as the 10CH(code value that is encoded to) in a certain step address, so after this coding is through (111), just will become the 10DH(code value and be-13), this coding is delivered in the 10DH address of (84), through encoded control with regard to the output voltage of generation-13V surely.Electricity each coding in waveform all multiply by behind the same multiple again through decoding, and each code value must all increase same multiple in the waveform so, so the amplitude of whole waveform has just increased this multiple, and the digital luffing technology of Here it is WRT.

The 5th of the WRT power supply is applied as formation and exchanges no hit supply unit.

Because some is important to be not allow momentary power failure with electric loading as computer facility etc., and it is very uneconomical with two Jiao stream Dian Yuan And alliance electricity, can only reach direct current at present and not have the hit power supply, even current state-of-the-art interchange UPS power supply also keeps away of short duration hit of unavoidable power supply and waveform sudden change, the solution of the present invention can realize exchanging no hit, waveform does not have the sudden change power supply.Figure 13 is for exchanging no hit tracking power supply schematic diagram.Its basic principle is: with WRT constitute one with the power supply (124) of electrical network same frequency with voltage, make (124) to follow the tracks of the variation of electrical network waveform again, reach same-phase completely, (124) just can be with electrical network to bearing a year And alliance so.In case when the electrical network dead electricity, (124) can realize not having the hit power supply.Among the figure, (120) be main power supply, (121) be phase detectors, its output lock-out pulse (122) is delivered to in the identical WRT power supply (124) of Figure 11, become the set end (123) of (100), make the Phase synchronization of (124) and (120), because frequency of (124) waveform that produces and voltage identical with (120) just originally, so waveform (124) just should be identical with (120), two power supply Ke Yi And through transport row.As needs, can increase matched impedance (125) in (124) and (120), be connected between two power supplys.Also should connect electronic failure circuit breaker (128) between (120) and the T feeder ear (127) in addition, avoiding after (120) fault, (124) not only to load (126) power supply, also may pass through (120) other electric on electrical network.Under (120) normal power supply situation, though two Jiao stream Dian Yuan And connection, because the internal resistance of (124) is bigger, so in fact (126) are mainly powered by (120), (124) power consumption is minimum.When (120) when breaking down, fault-signal (129) triggers (128) immediately and opens circuit, (124) just do not have impact, replace incessantly (120) to (126) thus power supply realizes no hit powers.When the battery tension in (124) dropped to certain minimum, (120) will be by charger (130) to (124) automatically charging, between charge period, (124) but produce waveform output while charge, to realize that exchanging no hit completely powers.

The 6th application of WRT power supply is the supply unit of non-stable electric energy feed-in electrical network.Its basic skills is: according to the appearance of electrical network waveform, the electric energy of the numeral system power supply that constitutes with astable electric energy by the analog or digital regulation technology of voltage, generates the output identical with the electrical network waveform, with this electric energy feed-in electrical network.Promptly, the shape information of AC network (131), after (132) (133), the sampling of (134) dividing potential drop, (be called for short A/DC through gain controller (135) to A/D converter again, 136) become the code signal of electrical network waveform, this coding is translated into control signal through (84), makes (33) to produce the voltage output identical with the electrical network waveform again after amplify (102).Capacitor (132) can be used to control phase, makes the suitable leading phase of generation make the waveform output of this device with electrical network suitable phase relation be arranged with the intrinsic time Yan Chi And that remedies the WRT system, so that best power factor is arranged when feed.Principle is seen Figure 14.

Astable electric energy (137) is generally the electric energy that natural the subject of knowledge and the object of knowledge such as wind energy, solar energy produces, as non-constant frequency amplitude-constant AC for wind-driven generator produced, can adopt the Chong Dian Dian Lu And of Fig. 6 to replace storage battery by capacitor, the frequency that at this moment can suitably improve alternating current is to reduce the cost of generator, transformer, energy storage capacitor.As be solar cell, unstable voltage dc such as thermocouple just can divide into groups battery, galvanic couple to connect by the structure of numeral system power supply in advance.

When the electric energy minimizing of (137) made each cell voltage step-down, though the constant rate between each cell voltage in the numeral system power supply, its absolute value unit voltage in other words will land even lower significantly.At this moment device as still press original control signal work, (33) waveforms amplitude of being produced also will reduce significantly so, and (33) can't operate as normal.Must use the feedback regulation technology for this reason, make the control signal that when (137) voltage changes, can make (33) produce corresponding the variation, to offset the influence of (137), the method of regulating has two kinds, a kind of is that the voltage signal (138) that (137) change is delivered to (135), when (138) (135) gain raising when amplitude reduces, the analog quantity voltage of delivering to (136) is increased, thereby the corresponding raising of the code value that makes coding, so that the unit that gating numerical value is bigger, the reduction of offset unit voltage is to the influence of output waveform amplitude, reach the stable purpose of output voltage amplitude that makes system with this, vice versa, and Figure 14 is exactly the method that this employing analog quantity regulation technology carries out voltage compensation.As the digital amplitude controller (112) that increases the multiplier (111) identical and control in (136) and (84) centre by (138) with Figure 12, then Zhuan Zhi output waveform amplitude will be controlled by exact figure regulation technology more, the performance of device will be better, the compensation scheme of the digital regulated technology of employing that Here it is.Except carrying out voltage compensation, can also regulate the phase place of waveform after the variation of electric energy in the unit, to change to the electrical network feeding amount.

This device also has than the advantage of prior art:

The inverter that prior art adopted can only astable electric energy change in voltage more among a small circle in to the electrical network feedback energy.After adopting this programme, because than being easier to, so astable electric energy can be to the electrical network feedback energy in big change in voltage scope by the digital technology control waveform.

2. this device has the ability from motion tracking electrical network wave form varies, so when voltage ripple of power network, the waveform of device is also and then done identical variation, energy back still can more stably be carried out, and also can not cause overload to device.Even when the complete decompression of electrical network, device and then is output as zero, also can not produce any danger, and automatic protection so cmpletely is that existing other inversion transformation technique itself is not available.

3. this device can be regulated power factor easily, so that each switch element of power part can be worked under comparatively ideal operating mode.

The 7th of the WRT power supply is applied as the omnipotent supply unit that formation is computerizedd control.

Whether the advanced person of laboratory or laboratory facilities, with the performance of power-supply device much relations arranged.Ward off as needing highly stable power supply sometimes, need the power supply that can quick and precisely suddenly change sometimes, need again sometimes can certain physical process of entirely accurate simulation power supply.Common function is mostly by various stabilized voltage power supplys, various signal generators, frequency conversion luffing high-power ac power, signal simulators etc. are born, but sudden change quick and precisely and accurately simulation be difficult to accomplish.In addition, the selection of so many power-supply devices, adjust, connect take out stitches also very inconvenient.As the omnipotent power supply of the WRT that computerizeds control, then an equipment just can replace many function, has the multiple specific function that produces by programming, and wiring, operation are also very convenient, are suitable for very much the laboratory and use.

Because computer has the ability of fast processing number, a large amount of storage of digital information, so the aforesaid artificial establishment to the random waveform control signal of this paper all can be carried out by common computer, automatically be translated into control signal as the sign indicating number value And that is calculated the permanent width of cloth sine waveform of constant frequency by computer, that is very easy.Figure 15 is for using the WRT omnipotent power principle block diagram of computer as controller, and (150) are computer, and (160) are its ROM memory, are used for storing compiler, application program and the control signal translator that is equivalent to (84) function of (150).(150) at first from (160), take out the application program of certain waveform according to the operational order of operation keyboard (157), working out out one group of waveform coding according to each parameter of this application program and (157) input then leaves among the RAM that is called waveform coding memory (161), the effect of this RAM is with Figure 12 (110), (161) waveform coding in is changeless in a kind of running status, but waveform coding also need be through certain digital processing (as arithmetical operation, logical operation, condition distinguishing etc.) to reach waveform is carried out amplitude control, the waveform requirement of processing such as compensated regulation to realize being scheduled to, treated waveform coding is translated into control signal by the control signal translator in (160) and leaves among another RAM that is called control signal memory (162), the control signal that leaves in (162) is not changeless, it will along with (150) input port (151) for information about, as feedback information (153), the variation of out of Memory (155) and half period half period ground changes.(162) just be equivalent to (84) in the precedent, in the gating arteries and veins that sends by the operation clock of being adjusted by computer (150) (not marking among the figure) successively preface gating (162) back amplify the synthetic required waveform of rear drive (33) through (102 ') in output port (152) output control signal.Because it is widely different that omnipotent power supply can produce the kind, frequency, the number of phases of waveform etc., should change the multi-channel filter (35 ') that this example has available switching into so can not use single filter (35) in former each example, send (35 ') so should add the drive signal (159) of filter in the driver (102 ').In addition, the waveform signal of the waveform signal of non-filtered and (36) output all can be used as feedback information (153) input (150) and realizes FEEDBACK CONTROL.The operation information of sending through the remote information (154) that can directly produce waveform output in addition and (157) of (151) input (156).The waveform graph of dateout (150) and (36) end all can be used as signal input demonstration and register (158) is made displayed record usefulness.

Operation keyboard (157) is gone up except that being furnished with the key that computer uses always, also disposes as the peculiar key of supply unit, as:

" direct current " key (DC, 171) is in order to produce the operation keys of voltage stabilizing direct current output;

" sine wave " key (SIN, 172) is in order to produce the operation keys of constant frequency amplitude-constant AC sinewave output;

" square wave " key (SQU, 173) is in order to produce the operation keys of the permanent width of cloth square wave output of constant frequency;

" triangular wave " key (TRI, 174) is in order to produce the operation keys of the permanent width of cloth triangular wave output of constant frequency;

" staircase waveform " key (STR, 175) is in order to produce the operation keys of the permanent width of cloth staircase waveform output of constant frequency;

" remote control " key (RMT, 176) is in order to produce remote control output is directly produced waveform output by (154) operation keys;

" special Wave " key (SPE, 177), in order to the key of the periodicity special waveform that produces artificial establishment or function waveform output, encoded radio can be by numerical key or peripheral hardware input (150), also can be left in (161) after by the functional expression establishment by (150);

" aperiodic wave " key (NPR, 178), operating function similar (171);

" frequency " key (F, 179) is in order to import the frequency values of required periodic wave;

" amplitude " key (A, 180) is in order to the effective value of input sine wave or the upper and lower extreme value (A of other periodic wave ₁, A ₂);

" pulse step number " key (N, 181) is in order to the step number of required what strobe pulses in instruction (150) each cycle, N=fs/F;

" number of phases " key (PHS, 182) is in order to the number of phases of input periodic wave;

" waveform number " key (WN, 183), the key of the number of the periodic wave that need to produce in order to input for example makes to make automatically behind 1000 sine waves of device output to be output as zero, will use this key.As then representing WN=∝ not according to this key, waveform lasts till that always device receives " stopping " instruction, just make be output as zero.

In addition, also have " starting " (STA, 185), " stopping " (STO, 186), " combined floodgate " (CON, 187), " separating brake " routine operation keys such as (DIC, 188).

Set forth its principle below in conjunction with operating instruction.For example, (150) adopt BASIC, require this supply unit to produce frequency F=50HZ, A=110V, PHS=3, the sinewave output of WN=1000.

Accept operational order by (150) behind (SIN) key, the indicator light in this key is bright, and button time and " SIN PROGRAM " printed words appear in (158) simultaneously.

By " F " key, successively by number key " 5 " and " 0 ", again by " READ " key, " F=50HZ " printed words appear in (158) then.

" press " A " key, successively by " 1 ", " 1 ", " 0 ", " READ ", "=", " READ ", " A appears in (158) then ₁=A ₂=110V " printed words.

By " N " key, then successively by " 3 ", " 2 ", " 0 ", " READ ", (158) occur " N=320 " printed words (this numeral can be optional in a segment limit by the performance of device, after N and F determine, clock pulse frequency fs=NF=320 * 50HZ=16KHZ).

By " PHS " key, successively by " 3 ", " READ ", PHS=3 " printed words appear in (158) then.Three groups (102) in the device, (33) etc. will be called and produce three-phase voltage output.

By " WN " key, successively by " 1 ", " 0 ", " 0 ", " 0 ", " READ ", " WN=1000 " printed words appear in (158) then.

By " CON " key, " CON " indicator light is bright, and load circuit is connected.(158) operating time and " CONNECTION " printed words appear.

By " STA " key, " STA " indicator light is bright, and three-phase voltage begins Zu He And output.(158) operating time and " START " printed words appear.

After the device operation 20 seconds, because WN/F=1000/50HZ=20 second just make up 1000 cycles, count down to 0 so the WN counter in (150) subtracts by 1000, send a STOP pulse automatically, device stops to export.(158) will print autostop time and " PROGRAM ENDED " printed words simultaneously.

If because overload makes the protective circuit breaker automatic trip of system, (158) will print trip time and " SHUT DOWN " printed words.

If because other fault makes the device can't operate as normal in the device, (150) can be by printing the numbering of detected trouble location or other fault detector indication together with sending fault time (158) to show from trace routine of not stopping.

Be the device function performed below according to aforesaid operations, (150) after receiving (157) operational order, will be F, A, N, each data such as PHS exist in the special-purpose RAM memory (not drawing among the figure), 1000D is arrived in WN counter set, the SIN application program that will be stored in simultaneously in (160) accesses, and this program can be worked out with different suitable language, and this paper is exemplified below with BASIC:

Program function

LET FS=F ^*N will obtain the strobe pulse frequency by F and N parameter

Fs=FN=16KHZ, (150) make the pulse of clock generating fs frequency.

DIM V(320) knows in the cycle by N and evenly be divided into 320

Step number also just has 320 control signals, so

Should in (161) and (162), stay respectively

Go out 320 memory headrooms, compile so that store waveform

Sign indicating number and control signal.

FOR S=O TO(N-1) calculates 320 magnitudes of voltage on the cycle waveform

320 waveform codings of being calculated are stored in (161), control signal translator in (160) is translated into 320 control signals and exists in (162), because the speed of service of computer is exceedingly fast, the whole procedure authorized strength work was just finished in the extremely short time.After starting " STA " key; (162) control signal in will add 1 operation by sequence of addresses one by one by clock command, and intact 320 steps of each run are got back to zero-address, and the WN counter subtracts 1 automatically; when this counter meter arrives zero, will send a stopping signal that is equivalent to " STO ".If " WN " key is not pressed, the WN counter is not worked, and the WN counter just null value can not occur, and waveform just will move down always.(150) receive the signal of keyboard after, except that sending the indicator light igniting signal, also send signal for showing and record to (158).

The accuracy of the waveform that each utility unit of the present invention is made up depends on the numeral system and the figure place of (33), and the data bits and the address size of (84) or (84 '), and figure place can enlarge as required, figure place is many more, the selected step number of each cycle is many more, alternative voltage number is also many more, and waveform is just accurate more.For the aperiodic waveform with certain waveform accuracy, the duration of one section waveform of establishment also can be long more on the other hand.For example, when needs are simulated certain physical quantity and carried out l-G simulation test by electric weight, just wish that the longer the better for the address of (161) and (162) in the device.If (161) and (162) be 16 bit address (they being the 64K internal memory), simulate 1 time/second slow variable quantity, then the waveform continuous output time is:

2 ¹⁶÷ 1 time/second

18.2 hour

Simulate 1,000 times/second fast variation variable, also can reach:

2 ¹⁶÷ 1000 times/second

1.1 minute.

By behind " aperiodic wave " key (178), 64K variable can be by hand or the peripheral hardware input, and after device moved, the simulated power electric weight that is equivalent to this physical quantity just can be exported by output.

The 8th of the WRT power supply is applied as the supply unit that replaces (33) in the 3rd, 4,5,6,7 each invention to constitute with the binary voltage synthesizer (33 ') in first application.

As seen from Figure 4, (33 ') are for adopting binary numeration system power source voltage synthesizer, have only three elements on each at it, promptly a null value diode (as 56) is represented the no-voltage on this, a unit (as 40) and a numerical value gating switch (as 48), 1 voltage on this position of switch closure interval scale.Know again that from the numeral system principle with the unit and the switch of as much, the voltage number that the binary system power supply is formed is maximum, can obtain 2 as n bit system power supply ^N+1-a kind of voltage.In addition, the control signal sign indicating number of (33 ') is identical or close with the address code of its general decoder (84), so (84) establishment is checked just relatively more directly perceived, requiring the not too high occasion of waveform voltage precision, (84) even can save and be combined into waveform with digital directly the control signal of waveform as (33 '), so the voltage synthesizer of being spoken of in each invention of this paper front (33) all can be replaced by (33 '), there is each invention of (84) can save (84).
