is one of core of this control circuit, and the change of electrode reversal of plate polarity is realized by adjusting the current potential height of level switch, It is described further below, when PB11, PA8 take high potential, the current potential rise in NPN triode C4 base stages, triode C4 conductings, three Voltage on level pipe C4 colelctor electrodes is close to the emitter stage of ground connection, and the voltage on PNP triodes Q1 is 0, triode Q1 conductings, MOS Voltage turn-on is obtained on pipe C7 grid, because PA8 is also simultaneously high potential, triode C8 is in the conduction state, so 12V is electric Pressure is grounded after R72, and metal-oxide-semiconductor C6 grid does not have trigger voltage, is closed, the arteries and veins for the input that

resistors, and value 10K ensures that the base stage of triode C4 during without switching signal remains low Level, drags down transistor base voltage, and electric capacity C75 values 104 or 103 can be filtered out during switch is switched on or off Shake, prevent from malfunctioning, resistance R20, electric capacity C75, pull down resistor R21 collective effects in triode C4 come conducting and pass It is disconnected, the 30V boostings for R10=470K Ω that triode C4 colelctor electrodes are connected by resistance, equally on transistor collector also PNP triode Q1 (model 3BW) base stage is connected to by resistance R14, so passes through triode C4 NPN (model 1BW) Turn-on and turn-off drag down or improve PNP triodes Q1 base potential, controller triode Q1 turn-on and turn-off, three-level When pipe C4 is not turned on, the voltage on triode C4 colelctor electrodes is approximately equal to 30V -0 .7=30V, 30V voltage effect It is less than the voltage of PNP triode emitter stages in R14 to base stage, is that can ensure PNP triodes Q1 by theoretical calculation Be not turned on, if triode C4 turn on, boosting gained 30V can pass through resistance R10 resistance eutral grounding, triode C4 current collections Electrode potential is approximately equal to 0V, and the collector potential of resistance R14 connections is equal to 0 V, and PNP triodes Q1 is turned on immediately, PNP Triode Q1 conducting turns on metal-oxide-semiconductor C7, and metal-oxide-semiconductor C7, metal-oxide-semiconductor C8 use LR024N, the conducting of N-channel MOS pipe with It is to have directly that shut-off, which depends on Vgs pinch-off voltages Ids, leakage current, LR024N switching frequencies, the device power of first device in itself, Relation, LR024N is selected here, the milliohm Id=25A of its voltage Vdss=60V Rds=35, Vgs=± 20V are complete Meet need of work, because its pinch-off voltage needs 20V needing follow-up booster circuit that DC12V voltages are raised, The turn-on and turn-off of N-channel MOS pipe can be controlled.Find that Vgs=DC12v is switchable metal-oxide-semiconductor C7 in actual use, electricity It is that metal-oxide-semiconductor C6, which is turned on and off, to be passed through in order to ensure that grid makes to be in reliable low potential without high level to hinder R15 connection grids Triode NPN C8 are controlled, and are also here to test and can use in actual test we used DC12V power supplies, DC12v By 1M Ohmic resistances R72 by NPN triode C8 colelctor electrodes to ground, button switch PA8 controls, 3.3V are similarly subjected to / 1K=0.3ma electric current, that is, to triode C8 base voltage be 3.3V when triode ON, three during equal to 0V Pole pipe turns off, and resistance R27, electric capacity C24, resistance R21, electric capacity C75 are similar to after PA11, and function is the same not to be described.Press Button PB11, PA8, it is a global switch in actual circuit, when PB11 connects 3.3V, PA8 meets 3.3V, works as PB11 During ground connection, PA8 ground connection, resistance R14 value 120K Ω；Resistance R88 value 1000K Ω.
