ABSTRACT:
An inverter apparatus and method having a restarting function at an instantaneous power failure includes a residual voltage detector for detecting a frequency and a phase of a residual voltage of an induction motor based on a direction of a current flowing in an induction motor connected to an output of the inverter apparatus by ON/OFF control of switching elements in an upper arm or a lower arm of an inverter portion simultaneously from a time after elapse of a predetermined period of time from occurrence of the power failure until a time of determination of restarting timing. A restart unit is provided for restarting the induction motor at the frequency and the phase detected by the residual voltage detector in determining the restart timing based on said residual voltage detector and the recovery timing of the power failure.
