摘要
为了克服传统电压型Z源逆变器控制中升压能力差、波形质量差等缺陷问题,提出了一种Trans-Z-S逆变器电路。研究了电路拓扑结构及升压原理,采用改进型SPWM调制策略(分别用不同的调制波调制开关管)控制改变输出电压,给出了MATLAB/Simulink下仿真结果,并搭建了基于Trans-Z-S网络的小功率单相逆变器的实验样机进行实验,仿真与实验结果验证了调制策略在Trans-Z-S逆变器的可行性。
To overcome such flaws as low boost capability and poor waveform quality in the control of traditional voltage type Z source inverters, this paper proposes a Trans-Z source inverter circuit. It discusses the topological structure and boost principle of the circuit, adopts an improved SPWM strategy {different modulation waves are used to modulate the switching tube} to control and change the output voltage, gives MATLAB/Simulink simulation results, and establishes an experimental prototype of the small power single- phase inverter based on the Trans-Z source network. Simulation and experimental results verify the feasibility of the proposed modulation strategy for the Trans-Z source inverter.
