Abstract :
This paper reveals the mechanism of output waveform distortion of high frequency deadbeat control PWM VSI with rectifier load through theoretical analysis. The stability of deadbeat control strategy is first discussed in detail. Then the limitation of load disturbance compensation used to reduce the THD of the output voltage waveform is illuminated because the feedforward precision will influence tracking reference voltage. Simulation and experimental results are demonstrated to verify the conclusion drawn in this paper
