Abstract: Novel three-stage algorithm of synchronous PWM control of five-phase inverter in the zone of overmodulation has been proposed and investigated. It provides smooth transition from linear modulation range to the ten-step operation mode of five-phase system at the maximum fundamental frequency, with full DC-bus voltage utilization. Simulations give the behavior of five-phase system during synchronous PWM control in the zone of overmodulation.
