摘　　要：为了克服传统DC/AC变换器不能实现软开关控制或者需要使用高频变压器的缺点,介绍一种新型组合式DC/AC变换器拓扑,并介绍其工作原理。从系统控制的角度,对新型DC/AC变换器进行研究,借助于PSIM仿真软件,比较不同信号频率和不同输入电压的设计效果,列出仿真参数,给出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。工频实验结果表明新型DC/AC变换器可以实现高频功率变换下交流逆变输出,证明理论分析的正确性。To overcome the disadvantages of conventional DC/AC converter such as difficult to realize soft switch con- trol and the need of high frequency transformer, a novel combined DC/AC converter topology is introduced and the converter＇s working principle is analyzed in detail. The control method applied for novel DC -AC converter is studied from the view of system control. The control effect of the given signal with different frequencies and different power in- puts are discussed by PSIM software. The parameters adopted in the realistic simulation, waveforms such as voltage of modulation reference and loact are given. The experiment results show the correctness of theoretical analysis and prove that the novel DC/AC convertor will achieve AC inverter output using High-frequency power conversion.
