| 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. |
