Abstract:
When at least one of power supply devices operating in parallel has failed to cause an overcurrent state, which in turn causes an overcurrent state in other power supply devices, operation of the power supply devices in parallel operation is stopped. When the operation of the power supply devices is resumed, operation of only the device which has failed is stopped by an overcurrent protection function prior to the normal devices. The normal devices do not reach operation stop due to the overcurrent state caused by the affect of the device which has failed, until the operation stop after the operation resumption.
