Abstract
A multiphase motor generator system includes a multiphase induction motor having a plurality of separate terminals, a multiphase inverter coupled to a DC link voltage source and the plurality of terminals of the multiphase induction motor, a plurality of current detectors configured to detect a plurality of currents that flow between the multiphase inverter and the plurality of terminals of the multiphase induction motor, and a controller coupled to the current detectors and the multiphase inverter, and configured to receive the detected currents and output a plurality of control voltages to the multiphase inverter. The controller includes a multiphase to direct-quadrature (dq) conversion unit, a dq equivalent unit, a dq to multiphase conversion unit, and a pulse-width-modulator (PWM) converter.
