A controller is described for a 3-phase PMSM that uses an open winding and a dual inverter drive with a floating bridge. The drive has a voltage boosting function that: extends the high-speed range of the PMSM; operates the main inverter bridge at unity power factor above the base speed; compensates for battery voltage fluctuations. The main features of the(More)
This paper investigates the most feasible configuration of a hybrid energy system for a typical electric-heated home in St. John's, Newfoundland. Available renewable energy resources data i.e. hourly wind speed, solar insolation and flow rate in Waterford River and electric power consumption data of an electric-heated house is used for sizing the hybrid(More)
A novel control scheme is presented for an open-ended winding motor dual inverter drive, where a primary inverter is supplied from a dc power source and a secondary inverter is supplied from a floating dc capacitor with no power source. Examination of the basic single phase equivalent circuit model of an induction machine reveals that near optimal motor(More)
Performance of a power electronic system is identified with its system efficiency, system cost, and the devices being used. This work illustrates how a Digital Signal Processor (DSP) based Pulse Width Modulation (PWM) switching scheme can be used as a low cost control solution to provide better excitation for the magnetic core of a 3-Limb Core Coupled(More)
