The principle of the circuit The car electric igniter consists of the voltage stabilizing filter circuit, astable multi-resonance oscillator and booster circuit, see as figure 7-132. The voltage stabilizing filter circuit consists of the filter capacitors of C1 and C2 and 3-terminal regulated circuit IC1. The astable multi-resonance oscillator consists of the resistors of R1 and R2, capacitors of C3 and C3, time-based integrated circuit IC2 and so on. The booster circuit consists of the LED VL, resistors R3 and R4, transistor V, booster transformer T and discharge capacitor C5.
