A direct flux controlled induction generator with space vector modulation for integrated starter alternator

A novel direct flux controlled scheme of induction generator has been proposed in this paper for future 42 V automobiles application. Fixed switching frequency and low torque ripple are obtained with space vector modulation. By controlling the stator flux linkage vector properly, the required DC bus voltage can be produced as well as the torque of induction machine. Simulation results show the feasibility of this scheme for the integrated starter alternator.
