“…Shifts of only a few µs lead to deterioration in the noise suppression effect of several hundreds of kHz. 6 As such, it is important to generate a switching signal that takes the terminal voltage during the dead time into consideration.…”

“…As such, if the switching signal is generated without considering the terminal voltage during the dead time, shifts equivalent to the dead time will occur in the rise time and the fall time of the terminal voltages of the two phases to be synchronized. Shifts of only a few μs lead to deterioration in the noise suppression effect of several hundreds of kHz 6 . As such, it is important to generate a switching signal that takes the terminal voltage during the dead time into consideration.…”

“…These methods involve adjusting the inverter switching to suppress fluctuation of the CM voltage. [5][6][7][8] In these methods, fluctuation of the CM voltage is suppressed by synchronizing the rises and falls of the terminal voltage across the phases of a power converter that includes a plurality of phases. In particular, it has been F I G U R E 1 Overview of two-motor drive system reported that, under the conditions that the amplitude and the frequency of the output voltage between two inverters are the same and are out of phase, the switching between the inverters will be out of phase and the conduction noise can be effectively suppressed.…”

This paper introduces a pulse‐width modulation (PWM) method for a two‐motor drive system that reduces the propagation of conduction noise to the power supply. This two‐motor drive system consists of two motors with two inverters, each of which is connected to a common DC bus. The proposed method suppresses the common mode voltage ideally to zero by shifting the rise and fall times of the output voltage of each inverter. Our experimental results show that the rise and fall times of the output voltage can be synchronized even when the two inverters are driven at different amplitudes and frequencies. We confirm that the proposed method suppresses the propagation of conduction noise to the power supply.
