650V SiC MOSFETs deliver lower switching losses for EVs and solar
Claimed to offer industry-leading efficiency to enable the next generation of electric vehicles (EVs), data centres and renewable energy systems.
The Wolfspeed 650V silicon carbide (SiC) MOSFETs have been added by Cree to expand its industrial portfolio. They are intended for use in a wide range of industrial applications to enable the next generation of EV onboard charging, data centres and solar and other renewable systems efficiency.
The 15 and 60mΩ 650V devices use Cree’s third generation C3M MOSFET technology, and are claimed to deliver up to 20 per cent lower switching losses than competing silicon carbide MOSFETs. According to Cree, they also provide the lowest on-state resistances for higher efficiency and power dense designs. The total cost of ownership is lower, says the company, through the more efficient use of power, reduced cooling requirements, coupled with what it says is industry-leading reliability.
Compared to silicon, the 650V silicon carbide MOSFETs deliver 75 per cent lower switching losses and a 50 per cent decrease in conduction losses which results in a potential 300 per cent increase in power density. According to Cree, design engineers can now meet and exceed the industry’s most ambitious efficiency standards, including 80 Plus Titanium requirements for server power.
The 650V MOSFET family is also suitable for on-board chargers (OBCs) in the EV market. The increased efficiencies and faster switching allow customers to design smaller solutions with added performance, claims Cree. The SiC MOSFETs also enable bi-directionality in OBCs without compromising the size, weight and complexity, adds the company.
Other industrial applications, such as general-purpose switched mode power supplies (SMPS) are also candidates for the 650V SiC MOSFETs.
The Wolfspeed 650V SiC MOSFETs are available now in surface mount and through-hole packages.
