Abstract

PURPOSE:To realize a compact and economical constitution of a device by connecting a single main power supply in parallel to plural secondary power supply units having the output capacity of each unit to be set optionally. CONSTITUTION:A main power supply M includes a voltage error amplifier 32 and a current error amplifier 37. Plural secondary power supply units S1-Sn have only current error amplifiers 371-37n that can optionally set the output capacity of each power supply unit. The source M is connected in parallel to the sources S1-Sn to form a DC stabilized powr supply of parallel operation type pulse width control switching system. The amplifiers 37 and 32 of the source M contain pulse width modulating partsIand II respectively, and the voltage information given from the part II is transmitted to each secondary power supply unit group. In such a way, the output capacity of the secondary power supply unit can be optionally set to realize a compact and economical constitution of the above-mentioned stabilized power supply.
