DSP-Based Sensor-less Permanent Magnet Synchronous Motor Driver With Quasi-Sine PWM for Air-Conditioner Rotary Compressor
博士 === 國立中山大學 === 電機工程學系研究所 === 100 === This thesis presented a sensor-less permanent magnet synchronous motor (PMSM) driver for controlling air-conditioner rotary compressor speed. In this thesis, a quasi-sine pulse-width modulation (PWM) driving method was proposed. Furthermore, the current feedba...
