Stress Engineering for Drive Current Enhancement in Silicon Carbide (SiC) Power MOSFETs

Cree Silicon Carbide Power White Paper: Cree SiC MOSFETs Enable LED Drivers with Unparalleled Cost/Performance

For high-bay and outdoor lighting fixtures, the cost of LED driver electronics is reported to be 17 percent of the total fixture cost. An additional 40 percent of the fixture cost comes from the mechanical, thermal and electrical portions of the fixture [1]. These portions help support the weight and volume of the LED driver, as well as protect the driver against surge events, such as lightning...

Cree Silicon Carbide Power White Paper: Highly Efficient, and Compact ZVS Resonant Full Bridge Converter Using 1200V SiC MOSFETs

Rev. Abstract The most recent version (C2MTM) of Silicon Carbide (SiC) devices is used in a Zero Voltage Switching (ZVS) converter application. A 1200V, 160mohm SiC MOSFET from Cree Inc. is used to design a high-frequency ZVS LLC resonant fullbridge (FB) DC/DC converter. With the outstanding advantages of SiC MOSFET, which has lower junction capacitance and low-on-state resistor compared to a s...

Thermal instability effects in SiC Power MOSFETs

Silicon carbide (SiC) power MOSFETs are characterised by potentially thermally unstable behaviour over a broad range of bias conditions. In the past, such behaviour has been shown for silicon (Si) MOSFETs to be related to a reduction of Safe Operating Area at higher drain–source bias voltages. For SiC MOSFETs no characterisation exists yet. This paper presents a thorough experimental investigat...
