Abstract

PURPOSE: To provide a voltage type inverter of a DC line current detecting system which can prevent the occurrence of a fault even when a driving motor is restarted in a zero-frequency state while the motor rotates.
CONSTITUTION: A means which outputs a full-phase 'off' signal to an inverter device for an arbitrary period at arbitrary time is provided. When a motor is restarted in a zero-frequency state while a motor rotates at a low speed, the output of the inverter device becomes a zero-vector output and a circulating current flows due to short circuit, but an overcurrent can be detected, since the circulating current is made to flow to the current detector 5 of a DC line by means of the full-phase 'off' signal.
