Voltage Distortion Analysis and On-line Compensation of VSI for Permanent Magnet Synchronous Motor

영구자석 동기전동기용 전압원 인버터의 전압왜곡 분석 및 On-line 보상

The a PWM VSI, the voltage distortion exists between the reference and output voltage. This distortion is caused by the intended blanking time and the inherent characteristics of the switching devices which are function of the operating condition. In this paper, the dead-time effects are analysed and a new on-line estimation method for a PMSM is proposed to compensate time varying dead-time effects
