인터리브드 PWM 방식의 6상 영구자석 동기전동기 전류 맥동 및 토크 맥동 분석 = Analysis of Phase Current Ripple and Torque Ripple of a 6-Phase PMSM Controlled by Interleaved PWM

다국어 초록 (Multilingual Abstract)

In this paper, phase current ripples and torque ripples of six-phase PM synchronous motor controlled by interleaved PWM are analyzed. The cause of the increase of phase current ripple in the interleaved PWM was mathematically analyzed based on the mutual inductance of stator windings and effective voltage vector. Simulation and experiment verified that the DQ current ripple and torque ripple can be reduced by interleaved PWM control. The FFT analysis of torque waveform confirmed that the magnitude of harmonic torque corresponding to double the PWM frequency was reduced.
