摘　　要：分析当前的单向混合三相电压型整流器(UHTPVSR)的拓扑结构和工作原理,并对其拓扑结构进行改进。提出基于T型中点钳位(TNPC)的单向混合三相电压型整流器拓扑结构,分别建立了Boost变换器和TNPC整流器的Euler-Lagrange(EL)模型,基于此模型,采用外环PI,内环无源的无源混合控制策略。在Matlab/Simulink中建立模型进行仿真,仿真结果说明无源混合控制策略具有强鲁棒性、动态性能好、抗干扰能力强等优点。The current topology and operating principle of the unidirectional hybrid three phase voltage source rectifier（UHTPVSR） is being analyzed, and its topology is being improved. The T-type neutral point clamped（TNPC） UHTPVSR topology is being proposed, and the Boost Converter＇s and TNPC Rectifier＇s Euler-Lagrange（EL） mathematical model being built respectively. Based on this model, the passivity-based hybrid control（PBHC） controller is being designed, which including the outer voltage loop based on proportional-integral（PI） control and the inner current loop based on passivity based control. The simulation model is established with Matlab/Simulink, and the simulation results show that the proposed control strategy has excellent robustness, good dynamic performances, and strong anti-interference ability.
