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 […]
