Figure 1: The Qorvo SiC FET – a ‘cascode’ of a Si-MOSFET and SiC JFET
The performance of wide band-gap (WBG) semiconductor switches such as silicon carbide cascode FETs (‘SiC FET’ henceforth) [1] (Figure 1) and SiC MOSFETs is closely tied to its package. At the pure technology level, nanosecond switching speed and low specific on-resistance result in very low losses, allowing much

For high-bay and outdoor lighting fixtures, the cost of the LED driver electronics is reported to be 17% of the total fixture cost. An additional 40% of the fixture cost is contributed by the mechanical, thermal, and electrical portions of the fixture [1], which, in part, help support the weight and volume of th

We expect utility services to be everywhere we are: charging our electronics in airports, flame-grilling our meals in restaurants, and filling drinking fountains in our public parks. To provide this level of service and convenience, utilities build networks of wires and pipes and communications channels th
