Title: Power source circuit and its electronic equipment
Inventor: TAKAMI HIROYUKI
IPC: H02M3/28
Filed: 1992-07-28
Abstract: PURPOSE:To enable input to be made or cut without recourse to the input voltage current of a circuit even if it is a low-voltage and low-current capacity of switch. CONSTITUTION:An input switch 9 is connected in parallel with a capacitor C1 for deciding the oscillation time constant of the oscillator 1 inside a control circuit 3. When this input switch 9 is in open condition, the capacitor C1 repeats the charge and discharge of a current, and the oscillator 1 performs the oscillation. Moreover, when the input switch 9 is in blocked condition, the capacitor C1 is short-circuited, and the charge and discharge time becomes zero, and the oscillator 1 stops the oscillation, and the control signal of a semiconductor element Q1 stops, so it follows that it stops the switching operation of the semiconductor element Q1, and it gets in open condition, and the circuit stops the supply of power.
