中文摘要：在稳压电源电路中，串联型稳压电源的调整管与负载串联，负载电流全部流经调整管，而晶体管的过载能力较差，一旦输出端过载或短路，输入电压全部加在调整管集---射极间，其电流剧增，使调整管猛烈发热，如果此时没有过流保护措施，调整管就要被烧坏，电源整流管也将受到巨大威胁或损坏。

In order to overcome the difficulty in estimating the ripple component on dc-side capacitor reference voltage, the modified control algorithm is proposed by ignoring the ripple component. Furthermore, the relation between control performance and damping coefficient is researched. In addition, the reasons of voltage source converter inner-loop control overmodulation are also analyzed. Based on the relation between control performance and VSC inner-loop input saturation, damping coefficient is adjusted on-line by fuzzy logic reasoning so that the trade-off between control accuracy and limitation of VSC inner-loop control overmodulation is solved preferably.
