SPICE model delivers SiC MOSFET benefits

SPICE model delivers SiC MOSFET benefits
A new SPICE model introduced by Cree increases the design-in support for the C2M Series SiC MOSFET power devices and demonstrates the benefits of Cree SiC MOSFETs—including the new C2M0025120D device, which recently shattered the on-resistance barrier by delivering 1200V of blocking voltage with an on-resistance of only 25mOhms—in circuit simulations.

BLDC motor driver reduces audible noise by up to 75%

BLDC motor driver reduces audible noise by up to 75%
Claimed to be the industry’s first 24V, sinusoidal, sensorless, BLDC motor driver, the DRV10983 has been announced by Texas Instruments. The motor driver uses 180°, sinusoidal, sensorless technology to reduce audible noise by up to 75% compared to competing solutions for applications such as cooling fans, ceiling fans, blowers and small appliances.

SiC power module boosts inverter efficiency

SiC power module boosts inverter efficiency
A 1.2kV all-SIC six pack module enables an increase in the power rating of inverters to 50 per cent while reducing power losses by 50 per cent to increase efficiency by 5 per cent. The device is based on Cree’s C2M SiC MOSFET and Z-Rec SiC Schottky diode technology. The all-SiC 1.2 kV, 20A six-pack features the industry’s lowest switching losses due to the zero turn-off tail current in the MOSFET and the zero reverse recovery current in the Schottky diode.
