基于CMV抑制的五相永磁同步电动机扩频SVPWM策略
CMV-reduction-based spread-spectrum SVPWM for five-phase PMSM
摘要
Abstract
To solve the problems of high common mode voltage(CMV)and severely conducted electromagnetic interference in five-phase permanent magnet synchronous motor(PMSM)with near-four-vectors-based space vector pulse width modulation(SVPWM),the novel CMV-reduction-based spread-spectrum SVPWM strategy was proposed.To reduce CMV,according to the CMV generation mechanism of the five-phase PMSM driven by voltage source inverter,the vectors in opposite direction were employed to replace the zero vector in the near-four-vectors-based SVPWM strategy.To restrain current ripple and conducted electromagnetic interference,the frequency of SVPWM was adjusted on-line based on the mechanism of current ripple and high-frequency harmonic distribution.The five-phase PMSM experimental platform was constructed to compare the proposed RCMV-3SVPWM strategy with the conventional NFV-SVPWM strategy,and the dynamic tracking performance tests were carried out on the five-phase PMSM.The results show that by the proposed strategy,the CMV can be reduced by 40％with decreased current ripple of 0.30 A,and the conducted electromagnetic interference is effectively suppressed with maintaining good steady-state and dynamic performance.关键词
