Abstract:

Accurate SPICE model of SiC MOSFET will play an important role in product simulation and testing.A modeling method of SiC MOSFET is introduced.The spice model of CPM3-0900-0010A is established and modified by combining automatic fitting with graphic correction technology considering physical meaning.The established model characteristic curve fits well with the measured curve provided by the product parameter manual.The key parameters generated in the modeling process are more consistent with the parameters provided in the product parameter manual,which improves the preciseness and accuracy of the simulation model.Compared with the actual test results,the fitting effect of the model is good,which can provide the basis for the simulation method of complex circuit with SiC MOSFET,and provide support for more accurate evaluation of the performance and system characteristics of SiC MOSFET.

Key words: SiC MOSFET, modeling, graphical correction, simulation, curve fitting
