Abstract

PURPOSE: To improve availability, by stopping an inverter upon occurrence of such external condition as deviating from the control capacity of the inverter, thereafter starting the inverter again automatically.
CONSTITUTION: In control method of an inverter, a circuit 2 holds a starting signal when a flip-flop circuit 1 is brought to device operation through a logic 1 or when a critical fault occurs in the device. A circuit 3 produces restart pulses when external conditions satisfy restart conditions after automatic protection stoppage. A circuit 4 for calculating DC voltage produced with a minimum allowable commutation margin time, comparators 5, 7, a circuit 6 for detecting over/under AC voltage and a time delay circuit 13 are provided, while furthermore, a circuit 8 for detecting AC overcurrent having critical fault level and DC overvoltage and over current detecting circuits 9, 10 are provided. It is judged whether external conditions are within the range of regenerative operation capacity, and operational sequence is set to provide automatic restart.
