【摘要】 本文提供了一种快速、简便的三相全控桥变流电路输出电压 Ud、晶闸管两端电压 UT 波形的绘制方法。该方法是直接利用整流变压器次级线电压波形来绘制 ,其关键是利用变压器二次线电压下标的两个字母及其变化 ,确定各个晶闸管的导通区间更多还原

【Abstract】 The papers offers a fast, simple and convenient way to protract deflector circuit output voltage wave U\-d of a three phase full controlled bridge and double end voltage wave U\-\{VT\} of a thyristor This way directly uses secondary line voltage wave of a transformer to protract, the key is to use the two subscript letters and its change of the secongary line voltage of a transformer to confirm conductive intervals of a thyristor更多还原
