SiC power module reduces weight in EVs
Designed for high current applications, Wolfspeed’s all-SiC power module in a 62mm module targets converters, inverters, motor drives, industrial electronics and EV systems.
The CAS325M12HM2 can realise efficiencies of over 98% and up to 10 times the power density compared to systems built with silicon-based technologies, says the company.
Operating at a higher switching frequency without any compromise in system efficiency reduces the number and size of magnetic and passive components required for the balance of the system. The thermal characteristics of SiC devices, packaging design and materials enable the module to operate at 175°C, says the company, which makes it suitable for industrial, aerospace, and automotive applications.
The module also offers a 66% reduction in module inductance to 5.5nH, compared to competitive power products at 15nH, says the company. This enables faster switching speeds, higher frequency operation, and low losses.
The module is configured in a half-bridge topology comprised of seven 1.2kV 25mΩ C2M SiC MOSFETs and six 1.2kV 50A Z-Rec Schottky diodes. The companion gate driver (CGD15HB62LP) is specifically designed to integrate and fit within the 62mm mounting footprint.
An engineering evaluation kit that includes both the module and the gate driver is also available.
