This paper presents the characteristics of pulse width modulation (PWM) patterns of a matrix converter (MC) under a high input power factor. The various PWM patterns of nine bidirectional switches for the MC can be established. All of the combinations of duty cycles with four commutations in three phases during one control period only using input voltage values under a high input power factor are derived. The PWM patterns of the derived duty cycles for low output voltage harmonics are evaluated. The characteristics and evaluations of the output voltage harmonics and switching losses for the PWM patterns have been verified by theories and experiments.
