Performance and Loss Analysis of Wide Bandgap Power Modules for High-Capacity Power Converters

Wide bandgap (WBG) technology-based Silicon Carbide (SiC) modules have emerged as an essential technology for power electronics converters. The SiC modules stand out for their improved efficiency, power density, and thermal stability in power converters. This is due to its remarkably low on-state resistance, temperature tolerance, and power loss reduction compared to traditional MOSFET and IGBTs. This research analyzed the characteristics of the latest 1200 V, 760 A, SiC power Module using mathematical and simulation models. The research proposes a 1 MW capacity-based efficient power converter using a proposed SiC module. PLECS simulation tool is used to compute the power loss analysis of the converter. The results improved the efficiency of the high-capacity power converters by 99%. The high-capacity converter can be used for various energy source applications, such as renewable energy, EV chargers, industrial power supply, HVDC, battery storage, power grids, etc.
