Abstract

PURPOSE: To achieve a parallel operation by providing a parallel operating function with a separate power supply all the time, supplying a stable power to a load from an inverter when the separate power supply fails, and automatically switching the inverter to the separate power supply to operate it in synchronization when the normal operation of the power supply is resumed.
CONSTITUTION: The output voltage and the frequency of an inverter 1 is matched with the output voltage and frequency of a separate power supply 2 such as existing power sources and the like and operated in synchronization. The output voltage and the frequency of the separate power supply 2 are always monitored. If they exceed the specified ranges, the separate power supply 2 is disconnected, and the inverter 1 is operated at its own specified voltage and frequency, thereby the power is supplied to a load 4. When the separate power supply has resumed the normal operation, and the voltage and the frequency are settled within the specified range, the inverter 1 is automatically switched to the separate power supply 2 and is operated with the separate power supply 2 in synchronization, thereby the parallel operation is achieved.
