A Silicon Carbide Based Bidirectional DC-DC Converter

Electrical power system upgrades for next generation ground combat vehicles require technology advances such as higher operating temperature, greater power density, and increased functionality. Silicon Carbide (SiC) based power electronic devices offer advantages over silicon devices, especially for high voltage buses, and Creare is currently developing a SiC based DC DC converter that operates at high power levels and temperatures. This approach minimizes size and maximizes lifetime and reliability. During Phase I we will demonstrate feasibility with comprehensive design, analysis, and computer-based simulations for electrical and thermal subsystems. During Phase II we will complete development and demonstrate a prototype in TARDEC’s System Integration Lab at TRL 6. Creare’s DC DC converter offers the benefits of higher power density and a simpler thermal management interface when compared to existing products.
