Cree: SiC 50-A module provides performance of 150-A silicon device

The Cree CCS050M12CM2 silicon carbide (SiC) six-pack module is the industry’s first all-SiC three-phase power module in an industry-standard 45-mm package. When replacing a silicon module with equivalent ratings, this six-pack module can reduce power losses by 75%, which leads to an immediate 70% reduction in the size of the heat sink or a 50% increase in power density. When compared to state-of-the-art silicon modules, the SiC 1.2-kV, 50-A modules deliver performance equivalent to silicon modules rated at 150 A. The switching of the SiC module allows significantly less derating than silicon IGBTs, which enables higher-frequency operation, both increasing fundamental output frequency and reducing passive component size in the motor drive. The SiC power module family can provide benefits to solar inverters, uninterruptible power supplies, and industrial power supplies.
