tap circuit

A developed welder, which outputs corresponding secondary voltage by different combination of original side of tap voltage transformer and voltage regulator, can output appropriate welding voltage through 3 phases bridge silicon rectifier circuit.

所研制的CO2焊机是由抽头式变压器原边和电压调节器的不同组合输出相应的副边电压.通过三相桥式硅整流电路输出适当的焊接电压。

During the design, we followed full-custom design methodology: confirm the spec-circuit design-simulation-layout design-tap out.

在设计中采用了传统的模拟电路设计方法：定制设计要求-电路设计-电路仿真-版图绘制这一自底向上的全定制方案。

Therefore choose positive and negative voltage regulating scheme as main circuit wiring scheme of on-load tap changer.

因此最终选择了正反调压方案作为有载分接开关的主电路接线方案。

The paper analyzes main problems of the mechanical tap changing switch of a transformer in practical use, presents the mechanical tap changing switch how to reform improvement and design of electrical control and relevant electrical circuit diagram.

本文从分析变压器机械式分接开关在实际使用过程中存在的主要问题出发，主要介绍了机械式分接开关如何改造成电气控制及相应的电气线路图的改进和设计。

The circuit and layout approved by Shenzhen Graduate School of Tsinghua University had been sent to tap out.

所设计的电路和版图通过了清华大学深圳研究生院测试审核，送交流片。
