摘要

通过理论分析，揭示了带整流负载的高频无差拍控制PWM VSI输出波形失真的机理。首先详细讨论了无差拍控制策略的稳定性。然后指出了负载扰动补偿用于降低输出电压波形的THD的局限性，因为前馈精度会影响跟踪参考电压。仿真和实验结果验证了本文的结论。

Study on the mechanism of waveform distortion of deadbeat control PWM VSI with rectifier load

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.
