Abstract

PURPOSE:To realize a constant level of the output voltage and at the same time to realize an even level for the output current of each switching power supply, by detecting the output current of each switching power supply and then feeding the output current to the control of each switching power supply along with the voltage detection signal. CONSTITUTION:The voltage signal D is detected through a voltage detecting circuit 6 which is common to each of the switching power supply operated in parallel. At the same time, the output current of each switching power supply is detected through a current detecting circuit 10 in the form a current signal E. Then the signal D and each signal E are added together through an adder 11 to obtain voltage/ current signals Fa, Fb-. These voltage/current signals are fed back to each power supply. As a result, both the stabilization of the output voltage 5 and an even level of output current of each switching power supply are attained at a time through the feed-back control.
