摘　　要：在分析了三电平二极管钳位式整流器拓扑结构以及工作原理的基础上,根据在a-b-c和d-q坐标系下建立的数学模型,设计了一种双滑模控制策略,并对控制系统进行仿真。仿真结果表明,与传统控制方法相比,直流侧电压的动态响应性能得到大大改善,实现了高功率因数控制,能够实现能量的回馈且网侧的电压电流波形平滑,验证了控制系统的准确性与可行性。Based on the three - level diode clamped rectifier topology and analysis of works on math- ematical models, through a rectifier at a -b -c and d -q coordinate system established to design double sliding closed loop control system, and the control system simulation. The simulation results show that, with the traditional use of PI regulated voltage and current dual- loop control system as compared to the performance of the dynamic response of DC voltage has been seatly improved, to achieve a high power factor control, and can achieve energy feedback voltage and current waveforms and network side good to verify the accuracy and
