New technique cuts costs of SiC high-voltage switches
Connecting several silicon-carbide MOSFETs in series may be a relatively inexpensive way of fielding high-performance power switches. So say researchers at North Carolina State University’s FREEDM Systems Center. The topology for the new power switches is called the FREEDM Super-Cascode. It combines 12 smaller SiC power MOSFETs in series to reach a power rating of […]
Choosing inductors for energy efficient power applications
Energy efficiency in power supplies can be as much about the inductors as about the circuit topology. A few simple calculations can prevent unpleasant surprises. CHRIS HARE, LEONARD CRANE COILCRAFT, INC. In high frequency dc-dc converters, inductors filter out the ac ripple current superimposed on the dc output. Whether the converter steps the voltage down […]
