| 摘 要： | 针对现有的三相全桥逆变器输出电压存在的动态性能差、对负载变化敏感等问题，提出了一种基于滑模控制的输出电压控制方案。为使电路能够在不同的载波频率下运行，文中采用了电压空间矢量脉宽调制三相逆变器拓扑结构，仿真结果表明该方案使得输出电压具有较小的总谐波失真，并具有较好的稳态性能和负载适应能力。

| Abstract: | In terms of the poor dynamic performance and sensitivity to load change in the output voltage of three phase full bridge inverter, a output voltage control scheme based on sliding mode control is proposed. In order to make the circuit operate at different carrier frequencies, taking advantage of the three phase inverter topology structure of voltage space vector pulse width modulation (SVPWM), the simulation shows that the scheme makes the output voltage has a smaller total harmonic distortion, good steady performance and strong load adaptability. |
