In the circuit, NE555 is the astable multivibrator with the oscillation frequency in 70KHz, and it uses the control input signal of reset pin (pin 4) to control its oscillation on / off state. When pin 4 input is in high level, the oscillator generates oscillation, and low level will stop the oscillation. The pin 3 of NE555 output can provide input voltage for the doubler rectifier circuit composed of VD1, VD2, C3 and C4 form provides the input voltage doubler rectifier circuit, then the output of the doubler rectifier circuit is about 8.5 V. Control signal can control VT2 on-off state, and the load of VT2 can be a relay.
