Abstract
An object of the present disclosure is to accurately simulate the operation of a CSTBT. The simulation model of a CSTBT includes a MOSFET, a diode whose cathode is connected to the drain of the MOSFET, capacitance Cconnected between a source and a gate of the MOSFET, capacitance Cconnected between a gate of the MOSFET and an anode of the diode, capacitance Cconnected between a source of the MOSFET and the anode of the diode, capacitance Cconnected between the drain and the gate of the MOSFET, and a behavioral power source Vconnected in series to the capacitance Cbetween the drain and the gate of the MOSFET. The behavioral power source Vperforms a switching operation when gate-emitter voltage Vof the CSTBT reaches a predetermined threshold value.
