This paper presents a new reduced order, closed form analytical model for predicting the switching behavior of the eGaN HEMTs. Design-oriented analyses of the equivalent circuit for each switching sub-interval during both turn on and turn off are carried out to derive a set of simple equations for all electrical quantities. These equations are such that they are expressed explicitly with the eGaN HEMT parasitic and equivalent circuit parameters, revealing more physical insight into the switching characteristics of the eGaN HEMTs. The model is validated with both simulation and experimentation.
