This paper focuses on the voltage modulation method to reduce the switching frequency and proposes a voltage-integral-based reference tracking modulation (VIRTM) method. The proposed method calculates an evaluation function by considering the factors of the switching frequency. Thereafter, the proposed method outputs the voltage vector based on the evaluation function and reduces the switching frequency. The switching frequency of the conventional discontinuous pulse width modulation (DPWM) and that of the proposed VIRTM are evaluated by using simulations and experiments based on feed-forward and feedback control systems. From the results, the usefulness and effectiveness of the proposed method are confirmed.
