Abstract

This paper proposes a digital PWM control technique for a segmented permanent magnet synchronous motor with multi-phase interleaved PWM inverters. A segmented motor with its segmented stator windings can be connected and excited by segmented PWM converters using multiphase interleaved PWM techniques. A phase shedding control strategy is developed for efficiency optimization when operating in light load condition. A digital PWM modulator with adjustable switching frequency and phase shift has been realized with FPGA. Analysis oriented simulation has been carried out for the loss analysis of the multiphase interleaved PWM inverter. Experimental verification has been carried out to show the improvement of the proposed digital PWM technique.
