Abstract
A heating element, such as a switching transistor, a choke coil, or the like, contained in a power supply apparatus, is arranged in such a manner as to be thermally coupled to a diode inserted in series with a power supply line. The heating element heats up in operation, causing the diode temperature to rise and thereby reducing the diode forward voltage drop.
