SImulation termination for SiC-base converter in simscape electriacal
I tried to use SIC MOSFET devices to build DAB converter, but it was difficult to converge. The model of the device I am using is CAS30012BM2 of Wolfspeed. Compared to ordinary MOSFETs, the characteristic is that the parasitic capacitance is very large. I cannot find a suitable solver configurtation to achieve stable operation. Even if I use discrete and open the local solver to run for a while, an error will be reported, and the waveform of the system will also be distorted. The reason why I think it is related to parasitic capacitance is because I can simulate correctly using the built-in MOSFET in Matlab under the default configuration of the solver. So I wonder how to set this simulation condition, because this circuit is not actually complicated. (I used the MATLAB version as 2020a). Thank you very much.I tried to use SIC MOSFET devices to build DAB converter, but it was difficult to converge. The model of the device I am using is CAS30012BM2 of Wolfspeed.
