Power source circuit for parallel operation

Abstract

Abstract PURPOSE:To prevent counterflow and to feed current uniformly to loads, by inserting a D.C. preventing means at the output side of power circuits to be operated in parallel and controlling the power source circuits to produce uniform output voltage. CONSTITUTION:Power source circuits A, B comprise converters 1, 1', anti- counterflow diodes 3, 3' connected in series to the output sections of the converters 1, 1', comparators 41, 41' for comparing load end voltage with a reference voltage fed from a reference voltage source 5 and comparators 42, 42' for comparing the output voltages of the converters 1, 1'. Control circuits 2, 2' receive outputs from the comparators 41, 41', 42, 42' and provide uniform output voltage from the converters 1, 1'.
