Abstract :
An advanced physics-based equivalent-circuit model of IGBT has been described featuring a high accuracy in predicting device electrical performance in real circuit applications. A SPICE Level 3 model is employed for simulation of the equivalent DMOSFET, while the voltage dependant drain- to-gate overlapping capacitance and drain ohmic resistance elements are modelled separately. The one-dimensional physics- based model of the low-gain BJT device is developed using the equivalent non-linear lossy transmission line sub-circuit. IGBT model is implemented in PSPICE circuit simulator and high accuracy of the model is demonstrated by comparing the simulation results with the electrical measurements of several test power circuits.
