Industry’s First All-SiC Three-Phase Power Module Alleviates Conventional Design Constraints
Cree, Inc. (Nasdaq: CREE) is introducing the industry’s first commercially available silicon-carbide (SiC) six-pack power module in an industry-standard 45-mm package. When replacing a silicon module with equivalent ratings, Cree’s six-pack module can reduce power losses by 75 percent, which leads to an immediate 70 percent reduction in the size of the heat sink or a 50 percent increase in power density. The new six-pack SiC module unlocks the traditional design constraints associated with power density, efficiency and cost, thereby enabling the designer to create high-performance, reliable and low-cost power-conversion systems. 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 efficient switching of the SiC modules allows us to use them with significantly less derating than silicon IGBTs,” stated Dr. Jun Kang, research and applications manager, Y ...
