Reduction of Torque Vibration in Integrated On-board Chargers Using Stator Windings of an IPMSM

This study proposed a control method to reduce the torque ripple vibration of an integrated on-board charger using windings interior permanent magnet synchronous motor (IPMSM). During battery-charging operation, stopping results in noise, as well damage and other components from caused by charging current. In method, generated was estimated back-electromotive force table, phase current controlled eliminate torque. The can suppress vibration, irrespective angle rotor IPMSM. effectiveness verified experimentally, with suppressed 94% compared that conventional method.
