Description

The double-purpose conversion source that matching is strong

Technical field

Belong to electronic technology field.

Background technology

Any outstanding electronic equipment is required for an outstanding power supply, just can become perfect product.

In electrical equipment, power supply may often be such that flimsy keypoint part, and the infringement caused with overvoltage of being struck by lightning is fault Main source, so reducing this power failure rate, is the most significant.

Present product makes rapid progress, and traditional power supply voltage regulation way has been not applied for the sci-tech product of modern innovation, Once multiple product about security personnel's equipment had been applied for such as this enterprise.The product of these equipment is the highest to the requirement of power supply, overcritical Degree will significantly larger than ordinary electrical home appliance, be inefficient by traditional design.Reason is as follows:

One be power supply be often electrical equipment, the most troublesome keypoint part, the most such to ordinary electrical home appliance.And to being furnished with electric power storage The product in pond is all the more so, because during with accumulator, and the most only load power source, add again the charging current filling accumulator, If accumulator electricity consumption is too much, initial charge stream is very big, thus more exacerbates the load of power supply, thus is easily damaged.

Two is the ordinary electrical home appliance same day at thunderstorm season, can pull out power supply prevention, in the needs used time, (if desired for seeing electricity Apparent time) because being easily alerted, can recover immediately, user is expected.And series products of ensuring public security is the most highly difficult, because dialling Behind power down source, being difficult to intuitively remind, because in the life of high rhythm, forget about that these things are possible, now its protection function is just Malfunctioning, produce security personnel's blank.If user is forgotten to recover, then security personnel will be in security personnel's blank for a long time.And present stable state collection Become in lightning protection, the most weak, as generally input ceiling voltage is only about 30 volts.

The particularity importance of three products being because security personnel, it is therefore necessary to have when design and adapt to electrical network change Wider, key benefit reason one is when voltage ripple of power network, will not originally penetrate integrated regulator and cause damage.Reason Two are, civil power relatively low or relatively high time can normal voltage stabilizing, do not result in the malfunctioning of protection function.Reason three is to make security personnel Product can have bigger use space.

Four is that security personnel's series products necessarily joins accumulator, and the maintenance of accumulator has higher requirement, wherein charging voltage It is worth different with place value.If load request voltage stabilizing is pressed in voltage stabilizing, then can not meet the requirement of charging, if by the voltage of charging As requiring, then load will be higher than normal required voltage for a long time.This is difficult point one.Difficult point two is if there being battery discharging system System, inevitable is formed or door power supply mode load with mains-supplied system, therefore both be loaded with or the circuit of door character. During battery discharging, most of time is often to save the standard value of 2 volts, and along with discharging, this value also to decline, the therefore output of accumulator Voltage drop is of great value, if or the pressure drop of circuit of door character excessive.The normal standard of deviation then loaded strengthens.Therefore use Any measure makes accumulator not produce too much pressure drop when electric discharge, becomes difficult point.Difficult point three is Set of system, and be that battery system is powered during without civil power, conversion between the two is to automatically switch, the most how could be real Now change scientific.Difficult point four is how to form two parts to power and be independent of each other each other, is i.e. when accumulator breaks down, no Mains-supplied system can be affected, otherwise do not interfere with battery system during mains-supplied system failure.Difficult point five, some data carry Going out and make to switch with relay, this scheme has multiple deficiency, and wherein the point of an important deficiency is power consumption, and difficult point six is, some Scheme cost is too high, is not suitable for the universal of product.

Just because of above-mentioned factor so that the development of power supply receives obstruction, the performance of electronic product to be made obtains more The most perfect, it is necessary first to be exactly the innovation of power supply, so needing brand-new thinking to carry out perfect to power supply.

The strong double-purpose conversion source of matching is by rectification unit, lightning protection unit, voltage-adjusting unit, accumulator, constant current Formula pulse charge unit, audion switch unit, switch control unit, load unit forms, and the response utilizing relay is rapid Property, when there being thunderbolt overvoltage, form fast tripping protection, AC voltage-stabilizing have employed the circuit form being automatically adjusted, steady to exchange Overvoltage or depression formation during pressure are automatically adjusted, and add the reliability of voltage stabilizing, use the section of constant-current type pulsed in direct current Learn charging modes, the life-span of maximized guarantee accumulator, measure is formed independent direct current current supply circuit, returns with Alternating Current Power Supply Road combines, and becomes the power supply in duplicate supply loop, and forms automatic switchover, owing to audion used is same type of big merit entirely Rate audion, thus easily mass, easily debug, so that this power supply has extensive and special purposes.

One, the characteristic of voltage-adjusting unit.

This unit is by voltage-reg-ulator tube (in Fig. 2 5.1), altemating trigger resistance (in Fig. 2 5.2), commissure resistance (Fig. 2 In 5.3), voltage-reference diode (in Fig. 2 5.5), amplifier tube (in Fig. 2 5.6), potentiometer (in Fig. 2 5.7), upper inclined point Inclined resistance (in Fig. 2 5.10) on piezoresistance (in Fig. 2 5.8), lower inclined divider resistance (in Fig. 2 5.9), benchmark, exchange every Form from diode (in Fig. 2 5.12):

It forms the principle being automatically adjusted: voltage-reg-ulator tube and amplifier tube together form mu balanced circuit accurately, former Because being that the base voltage of amplifier tube is a definite value, be i.e. emitter voltage add 0.7V(because the base voltage of audion all the time More 0.7V than emitter voltage), and lower inclined divider resistance, potentiometer, upper inclined divider resistance is connected jointly becomes a dividing potential drop electricity Road, if the output voltage of voltage-reg-ulator tube is too high, then the base current of amplifier tube is the biggest, thus amplifier tube collector current is just Greatly, the base current of voltage-reg-ulator tube is shunted the biggest, thus the output voltage of voltage-reg-ulator tube is reduced by, whereas if Output voltage is too low, and the base current of amplifier tube reduces, and amplifier tube collector current reduces, and the base current of voltage-reg-ulator tube increases Adding, so output voltage just improves, therefore defining adjustment automatically, so after potentiometer reaches required design load, making In with, the overtension or too low of voltage-reg-ulator tube output, can be formed and be automatically adjusted, add the reliability of voltage stabilizing.

In this unit, do not use 78 conventional series, and voltage-reg-ulator tube all uses with amplifier tube high back-pressure high-power Audion, topmost benefit is, audion high back-pressure, and far beyond the technical specification of 78 series only 30 volts, lightning protection effect is good. Also there is the feature that voltage regulation result is good simultaneously.Thus improve the reliable life of power supply source.

There is the explanation of wider mains input voltage.

The scope that civil power is wider can be operated in.

Being high-power high countervoltage triode in circuit, the back-pressure of its colelctor electrode may be up to 300 volts, so mains transformer The voltage of secondary side can be suitable higher, when therefore civil power is relatively low, the voltage of the secondary side of mains transformer remains to meet device The requirement of part.And when therefore civil power is higher, its rectification output is still not above 300 volts, thus it is unlikely to overall channel power supply Penetrating in Ji damages with pipe.So the present invention can be operated in electric hypodynamic place, and in the too strong place of electric power also Without compromising on.

It is difficult to damaged when unexpected fluctuation occurs in civil power.

Also because of above-mentioned reason, so when civil power unexpected fluctuation, will not damage easily.

Two, this utility model has the explanation that overvoltage protection is good.

There is good anti-overvoltage protection explanation: the lightning protection stabilivolt that protective relay is connected suctions through, and its correspondence is normally closed Contact disconnects, and rear class is formed protection quick-break, therefore to protected effect of being struck by lightning, forms a kind of special protection.This protection shape The principle become is, cut off rear class rather than short circuit, so good effect, at numerous equipment of many Compact Power Plants Lightning protection, it is simply that use this fast tripping protection.The stabilivolt connected due to protective relay is flexible, it is possible to form institute The anti-overvoltage grade needed.This lightning-arrest pipe being common is difficult to, because the lightning-arrest pipe of less than 100 volts is difficult to buy, and The anti-thunder tube of less than 50 volts almost can't buy.

The explanation of three, independent charge circuit feature, the i.e. explanation of floating charge unit.

It not in high-grade pressure stabilizing device, it is difficult to ensure that there is the accumulator of floating charge with civil power is powered simultaneously, there is height The unification of degree.This measure have employed special design, by completely separable with load circuit for the most supporting floating charge loop, thus tool There is good advantage.Now as a example by load needs 12 volts, if the accumulator of adapted 12 volts.Then during accumulator floating charge, need About 13.8 volts, if not designing special circuit, then when civil power has electricity, power output end is about 13.8 volts for a long time, and this is right The load only needing 12 volts is unfavorable.If power end output is adjusted to 12 volts, though load request can be met, but departing from accumulator Needed for floating charge 13.8 volts.Accumulator floating charge and discharge cell is devised for this native system.Its floating charge principle is that civil power has electricity Time, bridge rectifier one output has electricity, through constant current triode, then returns to the ground connection of bridge rectifier one through accumulator End, is also the negative terminal of accumulator, thus forms floating charge independent loop, according to kirschner law, and the experiment of circuit, this floating charge is returned Road is self-existent, does not interfere with each other the current supply circuit of load with ac power supply circuit, the ac power supply circuit confession to load Electricity loop is the output electric current of bridge rectifier two, through voltage-adjusting unit to load, is then return to ground wire, that is to say bridge The earth terminal of formula rectification circuit two.

Accumulator uses the pulse charge form of constant current mode, accumulator achieves science charging, enhances maintenance, extend Life-span of accumulator, decrease scrappage.

1, the principle of constant current is formed.

Floating charge to accumulator, have employed the form of constant-current charge, to ensure capacity and the service life of accumulator.

Constant current triode (in Fig. 2 8.1) is large power triode, its back-pressure value >=300V, therefore has the strongest reliable Property, it is connected to current limiting tube (in Fig. 2 8.3) between base stage and the other end of constant current resistance of constant current triode, the work of current limiting With, when load current is excessive, and when having exceeded the threshold value of current limiting tube, base current will shunt, and be no longer pass through constant current triode and put Greatly, hereby it is ensured that emitter current is certain value, thus become a kind of constant-current source.Why with two Diode series, it is Because the PN joint of audion is 0.7V, save equal to the PN of a diode, so need to be with two Diode series.

Constant current can be adjusted by emitter stage connected constant current resistance (in Fig. 2 8.2).

It is that circuit is simplified by the benefit of such circuit, reliably, beneficially engineering, the most cost-effective.

2, the reason of pulse is formed.

In charging with stopping filling the charge rule coexisted it is, within a cycle of pulse, when pulser is (in Fig. 2 10.11), during output low level, charging controls audion (in Fig. 2 10.27) and disconnects without trigger voltage, and its current collection is the most high-order, Thus charging controls diode (in Fig. 2 10.29) and do not acts on, constant current triode (in Fig. 2 8.1) is open-minded, fills to accumulator Electricity, when pulser output is high-order, through the transmission of extra pulse diode (in Fig. 2 10.25), makes charging control audion and leads Logical, its colelctor electrode communicates with emitter stage, current collection extremely low level, and now charging controls diode and the base stage of constant current triode clamped Position, causes constant current triode to be closed, and stops charging, and such charging modes is conducive to the scientific maintenance to battery, simultaneously to The battery damaged also has a certain degree of restitution.

The reason forming so charging is: when accumulator underfill electricity, stops filling device (in Fig. 2 10.21) and is output as Low level, because the voltage of in-phase end the most not up to stops to fill stopping filling in comparison inclined resistance (in Fig. 2 10.22) and stopping of device end of oppisite phase Fill the comparison voltage that under comparison, inclined resistance (in Fig. 2 10.23) is formed, so it is output as low level, thus stop filling control two poles Pipe can be considered off state, and charging now controls the change of audion and changes according to the vibration of pulser, when pulser Starting of oscillation, oscillation resistance (in Fig. 2 10.15) charges to oscillating capacitance (in Fig. 2 10.16), the homophase termination of pulser Pulse ratio relatively go up inclined resistance (in Fig. 2 10.12) and pulse ratio relatively under the pulse ratio that formed of inclined resistance (in Fig. 2 10.13) Relatively voltage branch, defines the threshold voltage of pulser, when the end of oppisite phase voltage of pulser reaches this threshold voltage value, and arteries and veins Rushing device output low level, charging controls triode ON, and current collection is the most high-order, constant current triode to accumulator to accumulator (in Fig. 2 9) charging, oscillating capacitance by oscillation resistance to pulser outfan discharge, when being put into the comparison less than pulser in-phase end During magnitude of voltage, a pulser output high position, it is low for trigger charging controlling audion, and the base stage of clamper constant current triode, accumulator is stopped Only charging, oscillation resistance starts again to charge to oscillating capacitance, and so circulation is until the magnitude of voltage of accumulator reaches to stop filling device always Till the comparing voltage value of end of oppisite phase.

Accumulator stops the principle filled: when the voltage floating charge of accumulator is to higher than stopping filling the comparison voltage of device end of oppisite phase, stop filling A device output high position, now no matter the output of pulser is high-order or low level, and charging controls audion and is all opened, this be due to Pulse diode with stop filling diode be by or door in the way of trigger charging and control audion, thus now charging controls diode All the time clamper constant current triode, until the voltage of accumulator is less than stopping filling the comparison voltage of device end of oppisite phase.

When accumulator is for stopping filling state, a trickle resistance (in Fig. 2 7) provides the trickle needed for maintaining to accumulator.

Four, civil power and accumulator duplicate supply explanation, its power supply trend is as shown in Figure 3.

When there being mains, bridge rectifier two exports high pressure, after voltage-adjusting unit, enters load unit Power end, conversion and control resistance by conversion and control audion trigger, therefore by the earth terminal of load unit, load current pass through The colelctor electrode of conversion and control audion, to emitter stage, because the grounded emitter line of conversion audion, has therefore been returned to ground wire, It it is i.e. the earth terminal of bridge rectifier two.

When mains without time, bridge rectifier two without output, voltage-adjusting unit without output, but now accumulator to Load unit is powered, and electric current is after load unit, through direct current switching audion (in Fig. 3 13.1) to bridge rectifier one Earth terminal, be i.e. the negative terminal of accumulator, complete power supply.

Five, the principle explanation of audion switch unit.

When mains sometimes, bridge rectifier two exports high pressure, and conversion and control audion (in Fig. 2 12.2) is touched Sending out, produce base flow, so conversion and control transistor collector has electric current, its current collection extremely saturation, its base loop is, bridge Formula rectification circuit two positive pole, through control unit transistor base to ground, collector current loop is, voltage-adjusting unit defeated Go out the colelctor electrode through load unit entrance conversion and control audion and then arrive ground.Now direct current switching audion oncontacting generating Pressure, that is to say without collector current, for off-state.

When without mains, bridge rectifier two, does not produces without electricity without output, conversion and control resistance (in Fig. 2 12.1) Raw base flow, so conversion and control transistor collector no current, its current collection extremely cut-off state, and the voltage of accumulator is through negative After carrier unit, direct current transition trigger resistance (in Fig. 2 13.1) trigger direct current switching audion (in Fig. 2 13.2), now Loop be that the anode of accumulator enters load unit through DC-isolation diode (in Fig. 2 9.2), then through overload list Enter the colelctor electrode of direct current switching audion after unit, the emitter stage of direct current switching audion enter connecing of bridge rectifier one Ground end, that is to say the negative pole of accumulator.

This utility model has a following significant advantage after implementing:

The quality of power supply, directly influences the performance of entirety.Power source performance is good, then overall performance is good.The one of particular importance It is that important equipment is generally equipped with Accessory Battery, as its scientific maintenance directly not affected the life of storage battery with reliable Property, it would be possible to become a kind of new trouble point, if if two is that the power supply parameter of supporting power supply is deposited with the power supply parameter of civil power Leading in difference, will directly affect electric property, three is that the automatic switchover performance needing two kinds of power supplys to be got well, to ensure each card signal Do not run off.Four is for ordinary electrical home appliance, and some important performances can make up with the behavior of employment, such as thundery sky, and can be artificial Pull out power supply, and a lot of equipment can not make up by artificial mode, such as the product of class of ensuring public security, pulls out power supply and just makes " security personnel " to become For blank, as being used in the equipment of signal transmission system, pull out power supply and can cause the unimpeded of system signal.What is more, sometimes people Also can not arbitrarily go to power-off source before equipment, pull out power supply.Details success, and the uncertain genus of the problems referred to above is thin Joint.This utility model is the regulated power supply that a kind of performance is the most excellent, and he has all excellent properties of current product, but also There is serial bright spot, therefore can be widely used for the needs of various electronic, the development that the adaptation electronic product moon new day is different Need.Concrete condition is as follows:

1, accumulator floating charge can remain to optimum state, uses the charged form filling not only but also stopping, has significantly being electrically charged pond Maintenance effects, some critics claim that chargeable battery is filled bad rather than damages on the net, and this measure can allow accumulator Charge relative maximum scientific maintenance, particularly to acid battery.And use such charging modes, the capacity of battery can not only be made Will not reduce with the life-span, even make defective cell can obtain a certain degree of recovery, so meaning is the biggest.

2, Alternating Current Power Supply is separate with accumulator, is independent of each other, thus further increases reliability, two Shi Dangwu cities Automatically switching during electricity, accumulator automatically engages immediately, and when there being civil power, accumulator is excised automatically.Switch speed is fast, because of controllable silicon There is strong positive feedback, thus switch performance is good, load will not be produced impact.Ensure that the performance of load.Three is power saving, The way with relay is proposed in some technical data, but relay very power consumption, the most unfavorable to supporting accumulator.

3, excellent performance, one is that anti-thunder is especially good with overvoltage protection effect, and during protection, relay normally-closed contact disconnects, to rear Level forms protection quick-break, cuts off rear class rather than short circuit, so good effect, and voltage-reg-ulator tube is the big merit of high back-pressure Rate audion, its back-pressure value >=300V.Two is that voltage regulation result is good, because being automatically adjusted of voltage can be formed, it is ensured that voltage stabilizing Effect.Having broader adaptation ability than traditional regulated power supply, occurring, unexpected voltage is high, will not damage.And it is relatively low at voltage Place also can normally work with the period.

4, two-stage output voltage (floating charge output voltage, with load output voltage) adjustability is strong, can extensively adapt to load Need.

5, simple in circuits, easily produces and debugging, and the debug point that reason one is because in circuit is few.Two are, the most easily quantify, because of It is same type of NPN audion for all of audion.Debugging scope is loose, workable.

6, cheap, wide adaptability, matching is strong.
