Using Situational Intelligence

John Reed, Space-Time Insight

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

SiC MOSFETs empower LED driver design

Marcelo Schupbach, PhD., Technical Marketing Manager, Cree, Inc

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
