摘　　要：提出了基于滑模控制的全桥式电压型逆变器的控制方法,解决了逆变器的电流基准不易测量的问题,并且在负载突变情况下,输出电压表现出对扰动的不敏感性和较强的鲁棒性以及良好的动态特性。给出了该滑模控制全桥式电压型逆变器在无刷双馈电机串级调速中的应用。应用表明,基于滑模控制的全桥式电压型逆变器输出电压能够快速跟踪参考信号。The control method of full bridge voltage-source inverter based on sliding mode control is the presented, which solves the problem of measuring current reference of sliding mode controller, and output voltage exhibits good dynamic property and robustness under load perturbation. The full bridge voltage-source inverter based on sliding mode control in application of BDFM＇ cascade speed is simulated by MATALB. The simulation results show that the output voltage of sliding mode control inverter can track the reference sinusoidal signal fast.
