ABSTRACT:
A power supply circuit for an audio power amplifier or an amplifier of similar operation such as a motor driving amplifier. The power supply circuit comprises a first coil having a first terminal connected to a terminal of a DC voltage source and a second terminal connected to an anode of a first diode, a second coil having a first terminal connected to another terminal of said DC voltage source and a second terminal connected to a cathode of a second diode, a first capacitor connected to a cathode of the first diode and the another terminal of the DC voltage, which accumulates a counter electromotive force generated in the first coil; a second capacitor connected to an anode of the second diode and the another terminal of the DC voltage source, which accumulates a counter electromotive force generated in the second coil; opening and closing device connected across the anode of the first diode and the cathode of the second diode, performing an opening and closing operation, and opening and closing control device connected to the opening and closing device, for controlling the opening and closing operation of the opening and closing device, and amplification device connected across a cathode of the first diode and an anode of the second diode.
