Detailed description of the invention
Fig. 1 is the utility model circuit diagram.
Specific embodiment
Utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, the utility model includes voltage-stabiliser tube ZD1, triode Q1, Q2, capacitor C1, resistance R1-R6, wherein surely
The grid of the positive termination minus gate voltage power tube of pressure pipe ZD1, the negative terminal of voltage-stabiliser tube ZD1 connect the base stage of triode Q1 through resistance R6, together
When through the base stage of resistance R5 connection power supply VCC, power supply VCC through capacitor C1 connecting triode Q1, the base stage and transmitting of triode Q1
Extremely directly simultaneously connecting resistance R3, the base stage of the collector connecting triode Q2 of triode Q1, power supply VCC is successively through resistance R1, resistance
The base stage of R2 connecting triode Q2, the base stage and emitter of triode Q2 is directly and the collector of connecting resistance R4, triode Q2 pass through
The drain electrode of power module connection minus gate voltage power tube.
Working principle:
Before minus gate voltage power tube powers on, grid voltage is low level (0V), and A point (voltage-stabiliser tube ZD1 negative terminal) voltage is clamped
For 5V (ZD1 is 5V voltage-stabiliser tube), at this point, triode Q1 base stage is high level, triode Q1 conducting makes the base stage of triode Q2
Point becomes low level, triode Q2 cut-off, triode Q2 current collection extremely high level, input power module control power module without
Output, the i.e. no positive pressure of the drain electrode of minus gate voltage power tube.
When powering on, the grid of minus gate voltage power tube powers on immediately, and grid voltage is high level (5V), A point (voltage-stabiliser tube ZD1
Negative terminal) voltage by it is clamped be 0V (ZD1 is 5V voltage-stabiliser tube), at this time power supply VCC give capacitor C1 charging, after capacitor C1 is full of, three poles
No-voltage, triode Q1 end pipe Q1 base stage over the ground, and when TTL over-pressure control end is high level, triode Q2 conducting, three poles
Pipe Q2 current collection extremely low level, control power module export positive pressure, i.e. the drain electrode of minus gate voltage power tube has positive pressure input.
TTL is electric control signal in minus gate voltage power tube positive pressure, is defaulted as high level.
