A new type of DC switch power which is possessed a DC voltage input and three DC voltage output, and is able to reach higher efficiency has been introduced in this paper.

本文介绍一种新型的直流开关电源，该电源是一种直流电压输入，三种直流电压输出，并能够达到相当高的效率。

As the frequency of the AC component increases, the DC meter response decreases, until at some frequency only the average input voltage will be displayed.

当交流分量的频率增加时，直流仪表的响应就会变得不够快，直到在某一频率时，仪表只能显示出输入电压的平均值。

If the AC voltage at the input is large, part of this signal is rectified, producing an error in the DC signal being measured.

如果输入端的交流电压很大，其一部分信号被整流，于是在被测的直流信号中产生了误差。
