Abstract

A power supply circuit includes a control circuit which outputs a control signal when an in-rush current flows and a power-supply-resistance control circuit which supplies a current to a capacitive load. The power-supply-resistance control circuit, provided in the current path between a power supply and the capacitive load, increases the resistance of the current path in response to the control signal and reduces the resistance of the current path in response to a stop page of the control signal, whereby the control signal is output or stopped so that the in-rush current is suppressed to a value smaller than or equal to a given value.
