Carrier-based PWM technique for three-to-five phase indirect matrix converters

Nowadays, multi-phase machines drives are considered in many applications, particularly for medium and high power application. This paper focuses on the three-to-five phase indirect matrix converter topology and the carrier-based PWM technique. This converter has the same characteristics as a conventional three-to-three phase indirect matrix converter such as sinusoidal input/output current waveforms, unity input power factor, no intermediate capacitor, simple commutation. The outputs of this converter are five phases with variable amplitude and frequency to supply a five-phase load. The carrier-based PWM technique is also proposed in this paper to control the three-to-five phase indirect matrix converter with the maximum voltage transfer ratio up to 0.7886. The proposed modulation method is developed from the study of a five-phase two-level voltage source inverter control. The algorithm can be easily implemented without computational complexity. Simulation and experimental results show the feasibility of the three-to-five phase indirect matrix converter and the proposed modulation technique.
