摘　　要：对最为实用的三相H桥串联型高压SVG进行深入研究。分析其拓扑结构及基本工作原理,用电容代替附加直流电源。介绍载波移相的调制方式,给出控制系统的结构图,并详述控制原理和控制过程。采用无功电流闭环控制,省去了一般PWM整流器所带的直流电压控制闭环。用MATLAB仿真整个系统,仿真实验结果表明:此控制系统的稳态、动态性能均达到预期目标。The dissertation deeply studied three phase cascaded H-bridge in mostly availability. The topology and the basic working principals were analyzed and exchanging the capacitance for additional DC power sources, then the methods of modulation of carrier phase-shifted was introduced as well as giving the controlling system structure diagram ,narrating controlling mechanism and process in detail. By the implementation of reactive current closed-loop control,the controlling of DC voltage with closed- loop used by average PWM rectifiers was omitted. At last the paper simulated the whole system with the software MATLAB, the results showed both the steady state and dynamic performance of control system achieved expected purpose.
