摘　　要：提出一种基于Buck变换的新型逆变器,通过建立电路的低频平均模型,用经典控制理论分析了该逆变器在各种经典控制方式下的稳态响应性能和暂态稳定性能,从而得到最优的控制策略———PD控制策略.实验结果表明该逆变器具有良好的暂态稳定性能和鲁棒性,从而验证了理论分析的正确性.A novel inverter based on the Buck conversion is presented. Then, a low-frequency mean-value model of the inverter circuit is established to analyze the steady and transient responses of the converter with different classic control methods by means of the classic control theory. The best control method named PD control is finally achieved. Experimental results show that the presented inverter is of good transient response and robustness, thus validating the correctness of theoretical analysis.
