摘　　要：电解电容是现代电力电子系统中用量多 ,体积大 ,可靠性差 ,寿命短的最薄弱环节。提出用高频电流型有源滤波器取代电力电子变流器直流环的电解电容 ,实现电解电容的“硅解”。实验结果验证了“硅解”方案的可行性 。Electrolytic capacitors are the most popular devices, but they have larger size, poor reliability and poor shelf life, so they are the weakest link in modern power electronic systems. This paper presents the application of a high frequency current type active filter for replecement of electrolytic capacitor in the dc link of an inverter, so as to implement 'silicon solution' of electrolytic capacitor. The experimental results show that the electrolytic capacitor can be substituted well by active filter.
