摘要
文章设计了双脉冲测试电路,可以方便地测量IGBT在实际电路中的开关特性与损耗,调节电感的大小与脉冲宽度,可以测试驱动电路的过流保护、短路保护、电压钳位功能,反映了IGBT在实际应用中的动态性能,同时可以计算平面母线的杂散电感,取得了较好的效果。
This paper designs a double pulse test circuit, it can measure IGBT＇s switching characteristics and power loss easily in the practical circuit, adjust the magnitude and pulse width of the inductance, and can test the overcurrent protection function, short circuit protection function, and the active-clamp function of the driving circuit, thereby reflecting the dynamic performance of IGBT in practical applications, furthermore it can calculate the stray inductance of the plane bus, and get a good effect.
