Abstract
An inverter device has a three-phase inverter for converting DC electric power into AC power for supplement to an AC electric motor and a control device operatively associated therewith, and the control device includes a phase current detection section for outputting a phase current waveform based on a DC input current and an operational processor section for performing operational processing for control of said inverter device based on the phase current waveform. Thereby, the inverter device can be constructed to be very compact.
