Abstract 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.
