Comparison of Bi-Directional DC/DC Converter using Si and WBG Devices

In this paper, the comparison of efficiency was done by using Si and wide band gap (WBG) material for bi-directional DC/DC converter in buck mode. The simulations were done with LTSPICE software. The Hardware setup was made using silicon and WBG MOSFET’s for DC/DC converter with varying resistive load for the constant output step down voltage. Each converter is designed using all silicon, all SiC and all GaN MOSFET’s for both software and hardware designs.
