Variable‐speed multiphase drive systems have become an increasingly important topics compared with conventional three‐phase one due to their distinct advantages. This study presents a new pulse width modulation (PWM) technique for controlling the three‐to‐five phase matrix converter to reduce the commutation number of the power switches and the total harmonic distortion, simultaneously. The proposed PWM technique provides full output voltage and frequency control in addition to unity input power factor by changing only five switch states during the control period. Moreover, it prevents direct switching or commutation between the maximum and minimum input voltages to reduce the switches voltage stress. 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 theoretically by using PSIM software and experimentally by using a laboratory prototype.
