摘　　要：以移相全桥ZVSZCS变换器作为控制对象,分析了平均电流模式的电压电流双闭环控制系统的控制原理,用MATLAB中的可视化工具SISOTOOL设计了电压电流双闭环的PI调节参数,减少了设计的复杂性和重复性。最后通过MATLAB/Simulink仿真软件搭建出电压电流双闭环控制系统的仿真模型,验证了设计结果的正确性。This paper first took the phase-shift full-bridge ZVSZCS converter as the control object , and analysed the control theory of the dual closed-loop with a current-loop and a voltage-loop based on the average current mode. Then it designed the parameters of PI regulator for the current-loop and voltage-loop using SISOTOOL, which reduced the complexity and repeatability for designing PI paramenters. Finally, it gave the simulation model of the dual closed-loop control system with MATLAB/Simulink simulation software. The experimental results show the design proposal is feasible.
