Abstract
There is provided a power supply circuit having a simple configuration which is capable of eliminating an adverse effect due to pumping operation. The capacitor-input positive and negative power supply circuit is comprised of diodes, switching circuits connected in parallel with the diodes, and control circuits that control the switching circuits such that the switching circuits conduct during a time period over which the diodes conduct.
