SiC power modules elevate energy efficiency

Six 2300-V baseplate-less power modules from Wolfspeed boost energy efficiency in renewable energy, energy storage, and fast charging applications. These half-bridge modules, optimized for 1500-V DC bus systems, are built on advanced 200-mm SiC wafers.

The 2300-V power modules not only enhance system efficiency, but also reduce the need for passive components. According to the manufacturer, they provide 15% more voltage headroom than comparable SiC modules, improved dynamic performance with stable temperature characteristics, and a substantial reduction in EMI filter size. Wolfspeed also reports a 77% decrease in switching losses compared to IGBTs and a 2x to 3x reduction in switching losses for SiC devices used for 1500-V applications.

Modules support a two-level topology, simplifying design and reducing driver count compared to IGBT-based three-level systems. This building block approach enables scalable power from kilowatts to megawatts and reduces potential single points of failure in a two-level implementation.
