This invention discloses an electrical power source, particularly the power source that can be regulated with its voltage conveniently, and can provide large range output of ac, dc voltage simultaneously, and provide also two routes continuous adjustable dc steady voltage (0-30v). The main point of the technical scheme is that an arbitrary number can be represented by 2n partial sum, so on the power panel are designed nine buttons: 20,21......28; when a voltage is needed, the corresponding buttons are pressed. With this scheme, 512 kinds ac voltage (OV-511V) output can be obtained. On the ac voltage output route added are a rectifier and a filtering circuit to achieve simultaneous ac/dc output. Two additional routes of 0-30v dc steady voltage are added to meet special requirements. The difference to ground is zero.

Technical field
The present invention relates to the supply unit of a kind of instructed voltage, pressure regulation, voltage stabilizing, more precisely is the multifunctional power that utilizes the number theory rule to be combined into more than 1000 kind of AC and DC voltage and to have the continuous adjustable direct current steady voltage of 0-30V.
Background technology
At present, the kind of power supply is a lot, but the adjusting range of voltage is very little, performance is not strong, all adopts fixed voltage output mostly, as 2V, 4V, 6V, 8V, 10V, 12V with six gear turn-knob switches, pressure regulation inconvenience, fragile.Chinese patent publication number CN1245303 discloses a kind of by changing the method that reference voltage changes output voltage; Chinese patent publication number CN3006660 discloses and a kind ofly can export 3V, 4.5V, 6V, 7.5V, 9V, 12V voltage, and can be to the power supply of button cell charging; Chinese patent publication number CN2457780 discloses and a kind ofly can provide 12V direct current and 110/220V alternating current; Chinese patent publication number CN1786558 discloses a kind of multifunctional power with hidden rotating lamp; Chinese patent publication number CN2686186 discloses a kind of multifunctional power that integrates welding, charges, starts.But up to the present, also do not have the pressure regulation easily of a kind of power supply on the market, can export two kinds of voltages of AC and DC simultaneously on a large scale again.
Summary of the invention
Can not make things convenient for pressure regulation in order to overcome existing power supply, and not have the deficiency of output friendship simultaneously, straight two kinds of voltages on a large scale, the invention provides a kind of pressure regulation easily, and can export the power supply of two kinds of voltages of AC and DC simultaneously.In order to solve the technical problem of above-mentioned existence, the technical solution adopted in the present invention is: utilize any one natural number of mathematical knowledge can be with 2
nPart and represent that designed multifunctional power, nine buttons on the control panel represent 2 respectively
0, 2
1... 2
8, required voltage is decomposed into 2 earlier
nPart and, press corresponding buttons on the power supply control panel then, output is required voltage.Add rectification circuit and filter circuit in the back that exchanges output circuit, so just can export two kinds of voltages of AC and DC simultaneously, and exported the potential to ground difference and be zero, can export the continuously adjustable direct current steady of 2 road 0-30V voltage in addition.
Beneficial effect of the present invention: only need nine buttons just can transfer more than 1000 kind of AC and DC voltage easily, increase the continuously adjustable DC voltage-stabilizing of 2 road 0-30V in addition and export, and the potential to ground difference is 0 that performance obviously is better than the combination of many instruments.

Embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment:
What (1) the present invention had at first solved power supply makes things convenient for the pressure regulation problem.Utilize any one natural number can be with 2
nPart and represent, on the control panel of power supply, designed nine buttons, represent 2 respectively
0, 2
1... 2
8, accompanying drawing 5, mutual inductance type transformer secondary output coil output voltage is respectively: 2
0V, 2
1V......2
8With 35V, 6.3V, 220v, mutual inductance type transformer secondary output coil is connected accompanying drawing 1 by certain logical relation with commutator.During use, earlier required voltage is decomposed into 2
nPart and, press on the control panel corresponding button then, just can obtain required voltage at output.For example: the user needs the voltage of 197V now.Utilize mathematical knowledge, 197=2
7+ 2
6+ 2
2+ 2
0The user presses button corresponding on the control panel then, and output is promptly exported the voltage of 197V.We only need nine buttons just can access 512 kinds of friendships, straight voltage respectively like this, independent simultaneously output 220 interchanges, purification, isolation voltage.
(2) second problem of the present invention's solution is exactly friendship, straight two kinds of problems that voltage is exported simultaneously.We have increased rectification circuit and filter circuit after exchanging output circuit, accompanying drawing 2 and accompanying drawing 3.Why to take two kinds of filtering modes,,, just must choose more high performance inductance and electric capacity if we take LC filtering though be because the LC filter effect is relatively good.Mixed economy and precision are considered, take the voltage in the 0-255V scope is adopted LC filtering, and voltage is in larger scope adopted L filtering.Accompanying drawing 2 is LC filter circuit figure: the pulsating voltage through rectifies passes through LC filtering again.The LC filter circuit is bigger or lessly all have good filter action at load current, and less to the impulse current of rectifier diode, so it is stronger to the adaptability of load.Accompanying drawing 3 is L filter circuit figure: the pulsating voltage through rectifies passes through L filtering again, and inductor filter adapts to the bigger occasion of load current, and little to the impulse current of rectifying tube.
(3) the 3rd problem of the present invention's solution can be exported the continuously adjustable DC voltage-stabilizing output of 0-30V exactly simultaneously.Address this problem the need of work of mainly using stabilized voltage power supply and electrical maintenance personnel based on the laboratory, accompanying drawing 4 is voltage stabilizing circuit figure.U
f, U
gEnd input 35V alternating voltage, the rectification of process rectifier diode and the filtering of electric capacity obtain the pulsating voltage about 40V, adopt well behaved LM317 tandem type integrated package of pressure-stabilizing, obtain the voltage of 1.25V in the output minimum, if it is adjustable continuously since 0, require this circuit to increase by one group of Ue, U in order to satisfy this
dEnd 6.3V alternating voltage, through 2cp10 halfwave rectifier and capacitor filtering, under the negative pressure accessory power supply of current-limiting resistance and voltage stabilizing, choosing voltage stabilizing didoe voltage is 1.25V, so anodal voltage to earth is-1.25V.The sample circuit potentiometer is not held with being connected on, but is connected on-the 1.25V end.When the potentiometer set to zero, ohmically+1.25V voltage is just and on the voltage stabilizing didoe-and 1.25V offsets, and output voltage is 0, and when potentiometer was transferred to maximum, output voltage was 30V.So just obtained 0 to the continuously adjustable DC voltage-stabilizing out-put supply of 30V.
