Breaking the Mold – SiC FETs as Circuit Breakers

Anup Bhalla, VP Engineering, UnitedSiC

Mechanical circuit breakers provide a secure means to make an almost lossless connection when on, and provide complete isolation when off, but they have their drawbacks. They are relatively slow to make and break and they arc across their contacts, particularly with DC, resulting in a limited operating life. Ne

GaN Devices for Smaller, Lighter, Smoother Motor Drives

Marco Palma, EPC

So far, silicon-based power devices have been dominant in the inverter electronics, but today their performance is nearing their theoretical limits. There is an increasing need for higher power density. Gallium nitride (GaN) transistors and ICs have the best attributes to satisfy these needs. The superior
