摘要
以开关电感准Z源逆变器为控制对象,采用一种新型PWM调制策略对其进行逆变控制。调制策略通过一个新的控制参数对直通占空比进行控制,实现了直通占空比与调制因子的解耦控制,增加了逆变器控制的灵活性,并在MATLAB/Simulink中进行了仿真验证。
This paper adopted a new PWM modulation strategy to control switched-inductor quasi-Z-source inverter,decouping the interdependence between the shoot-through duty ratio and the modulation index. And the shoot-through duty ratio depends on a new control parameter,which promotes the flexibility of the inverter control. It simulated in MATLAB/Simulink to verify the strategy.
