Novel PWM technique for three-to-five phase matrix converter

Multi-phase (more than three-phase) converters, required mainly for feeding variable speed multi-phase drive systems, are seen as serious contender to the existing three-phase drives due to their distinct advantages. This paper presents a new PWM technique for controlling the three-to-five phase matrix converter in order to achieve minimum switching loss and minimum harmonics, simultaneously, by reducing the number of switching commutation. The proposed PWM technique prevents direct switching or commutation between the maximum and minimum input voltages while performing the load voltage in order to reduce the switches voltage stress. Also, the proposed PWM technique of the matrix converter provides full output voltage and frequency control in addition to unity input power factor. Moreover, the proposed PWM technique provides output voltage ratio equal to 78.86 % of the input voltage. The effectiveness of the proposed control scheme has been verified using Matlab/Simulink software.
