Abstract

PURPOSE: To eliminate wasteful power consumption by detecting the malfunction of a power switching element in an inverter in a state that the operation of an inverter is stopped, and stopping the power supply to the inverter.
CONSTITUTION: If power switching elements 9-14 which are short-circuited exist in an inverter 2 even if all the elements 9-14 are set to OFF, voltages generated at connecting terminals 2a-2c to the inverter 2 of a motor 1 are largely deviated from the value of approximately 1/2 of the voltage applied to the inverter 2. Accordingly, when an operation controller 4 detects the voltage, power supply to the inverter 2 is interrupted. Thus, abnormal heating due to an overcurrent, unnecessary power consumption can be prevented.
