Abstract
A saturation control unit for an interphase transforming unit is provided. The interphase transforming unit has a primary coil and a secondary coil which are magnetically coupled via a magnetic core member. The saturation control unit includes a minimum detecting unit and a maximum detecting unit. The minimum detecting unit detects a minimum value of a magnetizing current of the interphase transforming. The maximum detecting unit detects a maximum value of the magnetizing current. A saturation estimating unit is provided for estimating an offset value of the magnetizing current. A saturation control signal generating unit is provided for generating a saturation control signal for the interphase transforming unit based on the detected minimum value, the detected maximum value, and the estimated offset value.
