摘　　要：通过分析交流Buck型动态电压调节器的工作原理和电路结构,考虑电路主要元件寄生参数影响,建立了其状态空间平均模型。在此基础上,以交流电压瞬时值作为实时输入信号,设计了输入电压前馈结合输出电压反馈的实时控制方案。在输入电压发生波动或畸变情况下,所设计方案能够有效抑制电压波动,消除谐波畸变,保持输出电压稳定,动态响应速度快。以数字信号处理器DSPIC30F4011为主控芯片,设计了实验样机。仿真与实验结果验证了所提出控制方案有效性。The state space-averaging model is obtained through the analysis of the working principles and the topology of the AC Buck dynamic voltage regulator. The control strategy using the AC voltage instan- taneous value as the real-time input signal and combined input voltage feedforward control with the output voltage feedback control is proposed. The designed voltage regulator can suppress the voltage fluctua- tions, eliminate harmonic distortions and stabilize the output voltage with fast dynamic speed when input voltage fluctuations or distortions occur. The prototype with digital signal processor DSPIC30F4011 is set up. The simulation and experimental results verify the validity of the proposed plan.
