      By building a single-tube efficiency simulation model, the advantages of SiC MOSFETs compared to Si MOSFETs are analyzed from the per-spective of power dissipation. Combining with Ansoft Maxwell finite element analysis, an equivalent model of the transformer suitable for effi-ciency simulation under a given operating condition was established. The efficiency simulation was performed based on the dual active bridge bi-directional DC-DC topology, and the efficiency difference was compared under different condition.
