Computational Efficiency Analysis of SiC MOSFET Models in SPICE: Dynamic Behavior

Transient simulation of complex converter topologies is a challenging problem, especially in detailed analysis tools like SPICE. Transistor models presented for SPICE are often evaluated by accuracy, with less consideration the computational cost model elements. In order to optimize application simulations, this research quantifies relative performance modeling approaches and contextualizes results regard accuracy. It well established that primary contributor semiconductor dynamic behavior voltage-dependent interelectrode capacitances. Therefore, study isolates these components resolve their influence on accuracy run-time. Both voltage-dependencies modeled, mathematic formulation chosen strongly capacitance models. addition factors, specific implementation within also determines performance. Through careful evaluation offers recommendations optimal implementations capacitances
