ABSTRACT:
A power supply circuit includes at least one capacitor, a plurality of switching members, a power supply which outputs a plurality of voltages and a selecting section for controlling said plurality of switching sections to periodically select one of said plurality of voltages and apply the selected voltage to one terminal and the other terminal of the capacitor. The selecting section includes a member for applying the selected voltage to one terminal and the other terminal of the capacitor across a resistor, during a current limiting period immediately after the application of the selected one of said plurality of voltages to one terminal and another terminal of the capacitor is started.
