While, the asymmetrical parasitic parameters of the wide-used laminated busbar can cause current imbalance for paralleled MOSFETs. The fast switching of SiC devices can further deteriorate the imbalance.

Specifically, six different coupling effects are investigated: the couplings between the inductor and capacitors, a filter inductor and trace loops, two filter inductors, two capacitor parasitic inductances, a filter inductor and ground plane, and two trace loops. Experiments were performed, theories were developed to investigate and characterize these parasitic couplings.
The three parameters Ciss, Coss, Crss appearing on MOSFET data sheets in general relate to these parasitic capacitances. On data sheets which provide separate descriptions of static characteristics and dynamic characteristics, these are classified as dynamic characteristics. These are important parameters affecting switching performance.
