All-SiC 300 A, 1.2 kV Half-Bridge Module Doubles Power Density and Enables Efficiencies up to 99 percent in Induction Heating, Central Solar Inverters and AFE Motor Drives
Cree’s silicon-carbide (SiC) technology continues to enable smaller, lighter, more efficient and lower-cost power systems with a new all-SiC 300 A, 1.2 kV half-bridge module. Packaged in industry-standard 62 mm housing, the new module reduces energy loss due to switching by more than five times compared to the equivalent silicon solution. This best-in-class efficiency enables for the first time all-SiC high power converters rated up to the megawatt level, extending Cree’s leadership in SiC chip technology into high current power modules.
”The drop-in feature of Cree’s new all-SiC power module allows us to achieve 99 percent efficiency while reducing the power module count by a factor of 2.5 in our existing HF induction heating systems,” said John K. Langelid, R&D manager, EFD Induction. “These benefits are greatly valued as a reduced cost of ownership by our end customers.”
The new all-SiC 62 mm half-bridge module’s game-changing switching efficiency and performance allow designers to reduce the amount of magnetic and cooling elements, delivering double the power density and a lower system cost while also reducing end user cost of ownership. Offering a simplified two-level topology that is feasible at higher frequencies, the new module can also eliminate the need to invest in multi-level silicon-based solutions.
The latest Cree® SiC power module is available with multiple gate driver options and is pin compatible to standard 62 mm half-bridge modules, including IGBT modules rated at 450 A or more. This allows designers to quickly and easily evaluate the module’s unparalleled capabilities.
The new all-SiC 300 A, 1.2 kV half-bridge module will be available as part number CAS300M12BM2 at preferred distributors like Mouser, Digi-Key and Arrow’s RF & Power Business, and will be priced at $451 each for 1,000-unit quantities. Companion gate drivers are also available from Cree and Prodrive.
