摘　　要：基于反向开关晶体管的特殊工作原理,设计了并联电阻法精确测量RSD的通态峰值压降。介绍了通态峰值压降的测量原理及过程,并确定了电路参数。实验结果表明:直径16mm的单片反向开关晶体管在1.2kA的脉冲电流(脉宽17.5μs)下测得通态峰值压降为8.0V。并且,反向开关晶体管通态峰值压降随换流峰值的增大而增大;改变分压电阻比值对测量结果无明显影响。The accurate measurement in parallel resistance to on-state peak voltage drop is designed based on the special principle of RSD.The measurement principle and process of on-state peak voltage drop is introduced,and the parameter of RSD circuit is confirmed.The experimental results show that the on-state peak voltage drop of RSD with diameter 16mm is 8.0V under the pulse current of 1.2kA（pulse width is about 17.5ms）.Besides,the on-state peak voltage drop of RSD is increased with the increase of peak current,and the ratio of two resistances has no significant impact on the measurement results.
