摘要 文中提出一种基于Buck变换的新型逆变方法,通过DC-DC变换实现逆变器的正弦波形输出,分析了电路的工作原理,并研究了该逆变器的控制策略、抗扰动性能、负载特性和动态响应特性等,仿真和实验结果表明,采用误差反馈PD控制,逆变器在输入直流电压或负载电流出现扰动时输出电压能保持动态稳定,且具有良好的负载外特性。与传统桥式逆变器相比具有低开关损耗、低成本等优点。 In this paper, a novel inverter based on buck converter is presented, which achieves a sine wave output voltage through DC-DC conversion . The author analyzes the circuit operation principle, studies its control strategy, immunity, load characteristics and dynamical response. The simulative and experimental results show that with the PD control based on feedback of voltage error the output voltage of the inverter can remain dynamically unchanged when there are disturbances in input DC voltage or load current, that the inverter has a good load characteristic. Compared with the traditional inverter, this new one has some advantages such as low switching losses, lower cost.
