Cree CPW5 Z-Rec diodes extend benefits of SiC into megawatt power systems market, improving efficiency and reducing cost
Cree, Inc. (Nasdaq: CREE) introduces the new CPW5 Z-Rec® high-power silicon-carbide (SiC) Schottky diodes, the industry’s first commercially available family of 50-amp SiC rectifiers. Designed to deliver the cost reduction, high efficiency, system simplicity and improved reliability of SiC technology to high-power systems from 50 kW to over 1 MW, these new diodes can address demanding applications that include solar / PV inverters, industrial power supplies, induction heating, battery charging stations, wind-turbine converters and traction inverters.
Developed to facilitate the direct matching of 50-amp diodes to 50-amp MOSFETs or IGBTs, Cree® CPW5 Schottky diodes reduce system complexity and cost by enabling the replacement of multiple low-voltage, low-current SiC Schottky diodes, or silicon PiN diodes, with a single CPW5 rectifier. Additional cost savings can be achieved through reduced maximum voltage ratings and the elimination of snubber circuitry d ...
