PURPOSE: To cause a plurality of converters, to be operated in parallel, to have redundancy and to make the size smaller by a simple structure. CONSTITUTION: A current detector circuit 10 for detecting the output current of each converter is connected in series on the secondary side of the transformer T1 of the converter, and connection is so made that the detected output of the current detector circuit 10 may be supplied to a maximum current detector circuit 14 and a self-current detector circuit 12. Each maximum current detector circuit of each converter to be operated in parallel is connected through the medium of a control wire CL, and connection is so made that the output of a self-current detector circuit 12 and the negative output of an maximum current detector circuit 14 may be added in each converter, and that this added output may be applied to the voltage control circuit of the converter. Each converter is controlled so as to adjust its output current value to the output current value of the converter which outputs maximum current. |
