Stromversorgung

摘要

A power supply system comprises plural converters being connected in parallel. Each of the current of plural converters is detected and each of the converters is controlled so as to match each of the converters to a maximum current value from among the detected current values. In the parallel operation converters, when some converter having an output current of zero by an accident is included, the remaining converters be partially charged equally a load current. Since a common bus is arranged between plural converters and plural loads, it is possible to carry out a redundant operation having a high reliability. Since a stable output can be obtained without affects by the fault converter, the power supply system having the redundancy and the high reliability can be attained.
