A feasibility study of electronic tap changers with active filtering function has been made. The simulation and the basic experiments gave the following results:(a) Safety operations that do not cause over voltages and short-circuit currents can be realized by the proposed commutations of electronic switches,(b) The third harmonic component contained in power line voltages can be decreased less than 1 %of the fundamental voltage by the proposed method controlling so that output pulse areas are proportional to those of the reference sinusoidal wave, and(c) To cancel the large amount of third harmonics requires large tap-voltages and it results to increase in capacities of electronic switches.The recent development of high voltage transistors will make the proposed devices put into practical use.

已经对具有主动滤波功能的电子水龙头更换器进行了可行性研究。仿真和基本实验给出了以下结果：（a）不会导致电压和短路电流导致的安全操作，可以通过提议的电子开关的拟合换向来实现，（b）电力线电压中所包含的第三个谐波组件可以减少较小的基本电压，从而取消了这些脉冲的脉冲效应，并且（否则）的基本效率是造成的，而犯罪脉冲的脉冲区域则是该脉冲效应的效果，并且（这些谐波）的参考效应率是在（这些脉冲）的范围内（以及（均可）。大量的第三个谐波需要大量的敲击电压，并导致电子开关的能力增加。最近的高压晶体管的最新开发将使建议的设备用于实际使用。
