Abstract
An inrush current inhibiting circuit is to inhibit an inrush current flowing to a load which includes an input capacitor and a pair of output terminals. The inrush current inhibiting circuit is provided with a switching element connected to the power source and on-off controlled, a first inductor connected between the switching element and a connecting point between the one output terminal and one electrode of the input capacitor, a diode whose cathode is connected to a connecting point between the switching element and the first inductor, a second inductor connected between an anode of the diode and a connecting point between the other electrode of the input capacitor and the other output terminal, and a control part for controlling the switching element.
