摘要
Z源逆变器用一个独特的阻抗网络将电源和变换电路相耦合,因而拥有常规逆变器所不具备的既能升压又能降压的特性。介绍了Z源逆变器的工作原理和运行状态,推算出Z源逆变器的升压原理。仿真结果证明了Z源逆变器的升压能力及若选取合适的阻抗网络参数可使Z源逆变器工作于所需要的状态。
Z-source inverter is an unique impedance network to take power source in coupling with converting circuit, thus it has the features either to make voltage up or voltage down which normal inverter does not have. Introduction was made to working principle and operating status of Z-source inverter, calculated voltage up principle of Z-source inverter. Simulation result proved voltage up capacity of Z-source inverter and if suitable impedance network parameters were selected, they will enable Z-source inverter to be in state needed for work.
