“…As for the motor drive application, especially the multi-phase motor, the thermal control for motor drive can also be adopted. For instance, the multi-phase Permanent Magnet Synchronous Motor (PMSM), it is widely used in servo applications in high reliability demand, for instance aerospace, electric vehicle and undersea equipment [3], [4]. Multi-unit, modular winding as well as redundant structure are effective ways to increase the reliability of multi-phase PMSM [5].…”

“…In [18]- [20], the SVPWM with modified switching sequence is used to reduce the noise in the range of human hearing, but the high-frequency harmonics cannot be eliminated. In application of twosegment three-phase PMSM, the interleaved technique with magnetically coupled inductors [21] and phase shift PWM technology [22], [23], are proposed, but two inverters are necessary. Additionally, some strategies involving carrier are reported to reduce high-frequency harmonics.…”

The underwater noise can be caused by the radial electromagnetic vibration of permanent magnet synchronous motor (PMSM) for electric propulsion. The difficulty in decreasing the underwater noise is not only the high-frequency but also low-frequency vibration reduction. This paper proposes a novel random asymmetric carrier pulse width modulation (RACPWM) method for PMSM vibration reduction in the whole frequency range. Instead of the conventional symmetric triangular carrier PWM, the asymmetric carrier PWM (ACPWM) is used to decrease the low-frequency phase current harmonics and the associated low-frequency vibration. Meanwhile, in order to suppress the high-frequency vibration, the RACPWM control based on the amplitude randomization of the sawtooth carrier is further presented to reduce the high-frequency phase current harmonics. Moreover, the RACPWM is equivalent to the random slope ACPWM in view of the output signals. Furthermore, without the need of any additional circuits in the drive, the presented method is simple to implement by software. Simulation and experimental results show that the proposed RACPWM method can effectively reduce both the low-frequency and the high-frequency vibration.

Pulse width modulation (PWM) technique brings harsh acoustic noise in motor drive system. Thus, synchronous random switching frequency modulation (SRSFM) technique based on carrier phase shift for paralleled three-phase voltage source inverters is proposed in this study to eliminate the PWM noise. The proposed SRSFM technique is able to remove the high-frequency PWM noise more effectively than the conventional random switching frequency PWM; it not only completely eliminates the PWM noise nearby odd-order carrier frequency but also reduces PWM vibration noise around even-order carrier frequency depending on the switching frequency variation range. Furthermore, the SRSFM technique is simple to implement and requires no additional hardware. Finally, the effectiveness of the proposed method is verified by detailed experimental results.
