    • A rush current suppression circuit is used with a power supply circuit which includes a common line and an input voltage detection circuit and supplies power from an input power supply via a switching circuit. There is provided a smoothing capacitor coupled to an output end of the power supply circuit, and a rapid discharge and delay circuit coupled to the input voltage detection circuit and carrying out a rapid discharge and a time delay and controlling the switching circuit. The switching circuit includes two FETs which are coupled in series to the common line, and the two FETs have sources which are coupled to each other and gates which are coupled to each other and driven by the rapid discharge and delay circuit.
