摘要
介绍了一种新型可升压的DC/AC变换器拓扑及其工作原理。从闭环控制和开环控制的角度,对新型DC/AC变换器适用算法进行了研究,借助于PSIM仿真软件,对采用滞环跟踪控制、PD控制和PI控制的效果进行了比较,列出了仿真参数,给出了负载电压,以及调制给定电压和变换器输出电压的仿真结果。仿真结果表明新型DC/AC变换器可以实现宽输入电压范围工频逆变输出,证明了理论分析的正确性。
A novel DC/AC converter topology and its working principle are first introduced. The control method applied for the novel DC/AC converter is studied from the open-loop and closed-loop control perspective. The control effect of the hysteresis tracking control, PD control and PI control are compared using PSIM software. Simulation parameters are listed with simulation results of load voltage, modulation reference voltage and converter output voltage. Simulation results show that adopting the novel DC/AC converter can realize invert output in power frequency with wide input voltage range, therefore prove the correctness of theoretical analysis.
