| 摘 要： | 针对电压型PWM整流器无源控制器设计中恒阻尼注入方法存在阻尼注入太小,导致启动变慢,稳态误差大,输出直流电压稳定性能变差;而阻尼注入过大,则导致输入电流总谐波畸变率(THD)值较大等问题,提出了变阻尼注入的无源控制策略,变阻尼注入采用跟踪微分器予以实现.通过选择合适的跟踪微分器非线性函数及其参数,可使阻尼按照期望值变化,使整流器的动静态性能进一步提高.仿真实验表明基于变阻尼的电压型PWM整流器无源控制策略是可行的.

| Abstract: | In the design of voltage-source PWM rectifiers control,when as the value of damper injection is too small,it induces the startup slow,static error increased,and the stable performance of the output DC voltage worse;if the value is too big,it induces input current THD greater.Aiming at these problems,a method of variable-damper injection is proposed,using tracking-differentiator to realize variable-damper injection.By selecting appropriate non-linear function and parameters,the dampers vary in term of expect... |
