New Energy Transformation Model for the Unclamped Inductive Switching (UIS) Test

摘要

Energy handling capability based on the inductive load is one of the major concerns for the automotive applications. In this paper, a new unclamped inductive switching (UIS) test model is proposed that accounts for the impact of inductance on measurements for the first time. During the measurement it is found that the inductance at the current ramp-up period is higher than that at the current ramp-down period due to the hysteresis induced inductance decrease. Based on two different inductances for two different periods, the UIS test model is proposed and validated that can well match with the measured experimental results.
