| Abstract(E) | In order to decrease air pollutant emissions, Electric Vehicles (EVs) have gained worldwide attentions and got popularized in an increasing speed. Motor drives power the EV including propulsion and auxiliary component such as power steering. Conventional three phase drives have been most widely adopted due to mature industrial standards and fair performance. Nevertheless, multiphase machines have become alternatives because they have beneficial characteristics such as great potential in fault tolerance and higher reliability. Thereby, this paper focuses on an asymmetrical six-phase drive, specifically equipped with 2 separate microprocessors for two sub-winding system. The two microprocessors provide integrated fault tolerance of the drive. Moreover, a novel current vector control scheme that utilizes observer to estimate the subsystem current for interference compensation against the magnetic winding sets has been proposed for its control. |
