Abstract
A multi-output-type stabilized DC power supply device using separately-exciting switching regulators which includes a single pulse generator. The output of the single pulse generator drives a DC-AC inverter and a plurality of pulse signals are obtained on a plurality of secondary windings of the DC-AC inverter. The pulse signals are distributed to respective pulse-width modulators of the switching regulators and are modulated thereat by respective error signals. The DC power of each pulse-width modulator is obtained by rectifying the pulse signal applied thereto.
