Abstract

The Open-Ended Winding Induction Machine - OEWIM - Drive with only one d.c. bus for both d.c./a.c. converters provide a path for zero-sequence current – ZSC - circulation. It can stress the semiconductor switching devices and the motor with undesired torque ripple if not addressed correctly. This work employs Rotor-Field-Oriented Control – RFOC - and hysteresis current control to limit the ZSC within the defined hysteresis tolerance band. Additionally, a switching limiter deals with the well-known issue of high switching frequency associated with hysteresis.
