半桥式可控硅逆变弧焊电源逆变过程的波形分析

本文通过对可控硅逆变式弧焊整流电源在半个周期中电压、电流波形的分析， 得出了决定逆变振荡频率的几个重要参数， 并由此推论出逆变电路中换向电容及变压器副边滤波电容设置的重要意义。

Waveform Analysis on Inverse Process of SCR Half Bridge Inverted Arc welding Power Source

This paper after analysing the voltage and current waveforms of a SCR inverted arc welding power source in half cycle, Several important parameters determining a inverse oscillate frequence are obtained in consequence the important significant on setling the change phase capacitance and the filter capacitance of a transformer secondary winding in a inverse circuit is deduced.
