Wolfspeed, Inc., the global provider of silicon-carbide technology, unveiled a silicon-carbide module designed to transform the high-capacity fast-charging sectors through improved efficiency, durability, reliability, and scalability.
The 2300-V baseplate-less silicon-carbide power modules for 1500-V dc bus applications were developed and launched using Wolfspeed’s state-of-the-art 200-mm silicon-carbide wafers. Along with other clean-energy applications, the new family supports Level 3 EV fast charging.
Wolfspeed’s 2300-V modules will improve system efficiency while reducing the number of passive components. They offer 15% greater voltage headroom compared to similar silicon-carbide modules, improved dynamic performance with consistent temperature stability, and a substantial reduction in EMI filter size.
Wolfspeed’s technology achieves a 77% reduction in switching losses over IGBTs and a 2-3x reduction in switching losses for silicon carbide devices intended for 1500-V applications.
Additionally, these modules will allow system designers to leverage lower cost printed circuit boards to cut manufacturing costs and significantly reduce development time compared to legacy bus bar solutions. They’ll enable the industry to adopt two-level topology, resulting in simplified system design and reduced driver count compared to IGBT-based three-level configurations. The benefits of 2300-V modules support a building block approach to easily scale power tenfold, from kilowatts to megawatts.
Currently, Wolfspeed is partnering with EPC Power, a North American utility-scale inverter manufacturer. EPC Power will be employing the Wolfspeed modules in utility-grade solar and energy storage systems, which offer a scalable high-power conversion system and high-performance controls and system redundancy.
