Abstract
Abstract In order to simplify electric phase agreement between mechanically initialized position and rotary electric machine of a turbochager with the rotary electric machine, when AC motor generator does not operate as a motor with rotating a rotor, the system of the present invention measures phase for polyphase of AC voltage, and measures mechanical position of AC motor generator by positional sensor, and criterion of polyphase AC voltage for driving AC motor generator as a motor from the measured value.
