POWER SUPPLY SYSTEM

Japanese Patent JP2833460

B2

PURPOSE: To obtain a stable output without being influenced by a failed converter by a method wherein the largest output current among the output currents of respective converters is detected and the respective converters are so controlled as to have their output currents agree with the largest output current.
CONSTITUTION: DC-DC converters Con1-Con4 are composed of forward converters. A control circuit CC detects an output voltage Vs1 and controls a switching device Mo with an output signal Gs1 to make the output voltage Vs1 a required value stably. The detection signal of a current detector Cs which detects the output current is inputted to the control circuit CC and a control line CL by which the largest current among the output currents of the respective converters which are connected in parallel with each other is detected and the respective converter currents are made to follow the largest current is connected to the control circuit CC. With this constitution, even if a failed converter whose output current is zero is included in the parallel converters, a load can be shared by the remaining converters while the failed converter is left as it is.
