SiC module cuts power losses by 75%

Cree has introduced a new silicon-carbide (SiC) power module, the CCS050M12CM, which it claims cuts power losses by 75% over silicon modules with equivalent ratings.

The 1.2kV, 50A six-pack module is available in an industry standard 45mm package. Cree says it delivers performance equivalent to silicon modules rated at 150A, enabling designers to create higher performance, lower cost power conversion systems. "The SiC power module family can also provide significant benefits to applications such as solar inverters, uninterruptible power supplies and industrial power supplies," commented Mrinal Das, product marketing manager for Cree's Power and RF division. "Even when designers simply substitute Si modules with SiC in motor drive applications, the improved performance of SiC reduces power losses, leading to reduced cooling requirements and, in turn, to a reduction in size, weight, complexity and the overall cost of the power electronics system."
