Abstract
Aiming at the crosstalk problem in photovoltaic grid-connected inverter，a crosstalk peak prediction algorithm for non-Kelvin packaged SiC MOSFET considering the effect of parasitic inductance is proposed. The half-bridge circuit composed of To-247-3 package SiC MOSFET is studied. Firstly，the mathematical model of crosstalk voltages in each stage are analyzed，and the differential expressions of crosstalk voltage are derived；Secondly，the prediction algorithm of crosstalk peak is proposed，and the mathematical models of the parameters required to predict the crosstalk peak are established；Finally，an experimental platform is built to verify the correctness of the theory and the effectiveness of the algorithm.
