Abstract

PURPOSE:To hardly trip by observing a DC voltage of a converter, and pausing an inverter operation when it decreases lower than the special value, thereby eliminating the occurrence of an abnormal operation even if a power is momentarily stopped. CONSTITUTION:A power source 19 receives power from a DC voltage VDC of a converter 14, and supplies power voltage to a base driver 18, a controller 17 and a DC voltage detector 20. The detector 20 detects whether the voltage VDC is higher than the specified value or not, applies a signal to the controller 17, sets an inverter to a pause state by an input voltage that a voltage stabilization does not operated in the full-load state, and resets the operation by the frequency immediately before entering the pause state when the input voltage is reset.
