Inrush current control for a capacitor that has a transistor whose collector circuit is connected in series, and a control means that controls the transistor based on the difference between a signal based on the voltage across the capacitor and a reference signal to control the inrush current when one source is turned on. A protection circuit for the circuit, which includes a comparator that compares the voltage across the capacitor with a reference value and detects a drop in the voltage, and is activated by the voltage drop detection signal of this comparator to control the inrush current of the capacitor. A protection circuit having a timer in the circuit control means that alternately generates a signal to cut off the transistor for a certain period of time and a signal to perform the original inrush current control operation for a certain period of time.
