Power converter control apparatus for multi-phase alternating-current (AC) generator motor of hybrid vehicle has control device with control selector that chooses generation voltage controller or generation torque controller

摘要

The power converter control apparatus has a control device (210) with a control selector (307) that chooses a generation voltage controller (305) or a generation torque controller (306) during power generation based on an outside command or the load of a multi-phase AC generator motor. The control device controlling on/off operation of the switching elements in a power conversion unit (220). The generation voltage controller controls the field current so that the B-terminal voltage in the multi-phase AC generator motor becomes equal to a generation voltage command. The generation torque controller controls the field current so that a generation torque in the multi-phase AC generator motor becomes equal to a generation torque command.
