Cree's Wolfspeed division has launched a series of rugged silicon carbide (SiC) equipment for the electric vehicle (EV) and renewable energy markets, mainly targeting on-board power conversion systems, off-board charging, and solar inverters And other outdoor applications.
Wolfspeed said that its E series is the first 900-volt silicon carbide metal-oxide-semiconductor field-effect transistor (MOSFET) and diode commercial series products that comply with automotive AEC-Q101 certification and production part approval process (PPAP), and are suitable for high humidity environments. Meets automotive quality standards and is both reliable and corrosion resistant.
Cengiz Balkas, General Manager and Senior Vice President of Wolfspeed, said: "The new E-series products provide automotive manufacturers with rugged, automotive-standard MOSFETs and diodes for on-board and off-board charging circuits, critical to the development of electric vehicle technology Important. The commercial promotion of the E series products makes Wolfspeed the first company in the industry to launch a full set of MOSFETs and diodes that can withstand high humidity environments, and its MOSFETs and diodes are very reliable, which can help promote the widespread adoption of automakers in the next generation of electric vehicles. The system-level value of silicon carbide. "
E series silicon carbide MOSFETs use Wolfspeed's third-generation rugged planar technology, which has been proven in the field for more than 100 billion hours. The 900-volt MOSFET in the E-system has the lowest switching loss and the highest quality factor in the industry. The E-system 900-volt MOSFET is optimized for battery chargers and high-voltage direct current to DC (DC-DC) converters in electric vehicles. Reference design for Wolfspeed's 6.6 kW directional car charger.
Its hybrid PIN Schottky diode (MPS) provides high reliability for automotive power conversion systems and solar inverters, and complements Wolfspeed's existing AEC-Q101-compliant 650-volt silicon carbide diode product line. The diode blocks voltages up to 1200 volts and is rated at up to 20 amps at temperatures up to 175 degrees Celsius. Its reference design includes a 20-kilowatt two-level AFE and DC-DC converter for external chargers, which reduces power consumption by more than 30% compared to existing three-level Vienna rectifiers.
