REDEXPERT loss simulation

Find the best inductor!

REDEXPERT has the world’s most accurate AC loss model, which even includes the DC-bias current. With dedicated DC-DC topologies or the generic loss simulator, you can accurately determine the AC and DC losses for your converter. The model includes the core material, shape and winding structure of the inductor. REDEXPERT recommends suitable inductors and allows you to add more filters to find the best inductor for your application.
