Abstract :
This paper reveals the mechanism of output waveform total harmonic distortion of high frequency PWM VSI with rectifier load through theoretical analysis. The conclusion drawn in this paper helps evaluate the effectiveness of different waveform synthesis techniques. Moreover the mechanism of waveform distortion suppression based on instantaneous feedback control strategy is discussed in detail. Simulation and experimental results are given to verify the conclusion drawn in this paper
