A NEW METHOD FOR CALCULATING THYRISTOR REVERSE RECOVERY CURRENT PARAMETERS
-
摘要: 本文从一组反向恢复电荷曲线和一组反向能耗曲线出发,给出了晶闸管关断模型反向恢复参数的一种新的计算方法.此方法的计算误差在di/dt和IF较宽的变化范围内,较其它的传统方法小得多.因此,此方法具有一定的实际应用价值.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.
