Abstract

PURPOSE:To simply construct an auxiliary power source by supplying the operating voltage of a controller from a battery at the time of starting a DC/DC converter and supplying it from the output of the converter after the starting. CONSTITUTION:An auxiliary power source 29 which supplies an operating voltage to controllers for an error amplifier 26, a pulse width converter 27 and a drive circuit 28 and the like is composed of a battery 30 and diodes 31, 32. The operating voltage is supplied from the power source 29 at the time of starting a DC/DC converter, and the output DC voltage is supplied as an operating voltage through the diode 32 at the time of starting the converter. Since the battery 30 may supply only the operating voltage at the starting time in this manner, it can be small capacity.
