低采样频率比下异步SVPWM的谐波畸变分析与抑制

Operation at low sampling-to-fundamental frequency ratios is challenging, but inevitable for high-speed electric drives due to the limited switching frequency. Synchronous modulation is commonly used to replace the asynchronous one to reduce harmonic distortion at these operation states. However, synchronous modulation faces the severe problems of poor dynamic response and intensive computation. T...
