一種計(jì)算晶閘管反向恢復(fù)電流參數(shù)的新方法
A NEW METHOD FOR CALCULATING THYRISTOR REVERSE RECOVERY CURRENT PARAMETERS
-
摘要: 本文從一組反向恢復(fù)電荷曲線和一組反向能耗曲線出發(fā),給出了晶閘管關(guān)斷模型反向恢復(fù)參數(shù)的一種新的計(jì)算方法.此方法的計(jì)算誤差在di/dt和IF較寬的變化范圍內(nèi),較其它的傳統(tǒng)方法小得多.因此,此方法具有一定的實(shí)際應(yīng)用價(jià)值.

Abstract: Based on a set of reverse recovery charge curves and a set of reverse energy loss curves, a new method for calculating the reverse recovery current parameters of the thyritor turn off model is given, In a wide range of di/dt and IF the error of this calcaiating method is less than that of the other traditional methods. Therefore, this method has certain value for actual applications. -
