摘　　要：为提高Z源逆变器升压能力同时减小电容应力,提出了一种电源嵌入式Z源逆变器的电路拓扑理论;采用了开关电感和直流电源嵌入分支电路的拓扑结构,通过分析该拓扑的储放能过程,及其基本结构和工作原理并利用MATLAB/Simulink仿真软件进行了验证。最后基于DSP-TMS320F2812控制平台搭建样机进行实验验证,仿真及实验结果表明,该拓扑结构是可行的准确的;在有效提高逆变器的升压能力的同时降低了电容电压的应力。To improve the ability of Z-source inverter booster at the same time and reduce the capacitance stress,a power embedded Z source inverter circuit topology theory is proposed,the switch embedded inductor and dc power supply branch circuit topology structure is adopted.Analysing the topology of store process,its basic structure and working principle,and using simulation software MATLAB/Simulink,the circuit topology theary is verified.Based on the DSP-TMS320F2812 control platform to build prototype experimental verification,the experimental results prove that the simulation results show that the topology is feasible and accurate.Ability to effectively improve the inverter’s booster at the same time reduces the stress of the capacitor voltage.
