Coupled inductor buck design

WebThey can be used as coupled inductors in various non-isolated DC/DC converter topologies or as transformers in flyback converters. A further application involves the use as common-mode inductors in power supply lines. TDK´s dual inductor series offer coupling factors up to 99%. The compact robust designs feature functional isolation voltages ... WebAn isolated buck converter, also known as Fly-Buck converter, is created by replacing the output filter inductor (L1) in a synchronous buck converter with a coupled inductor (X1) or flyback-type transformer, and rectifying the secondary winding voltage using a diode (D1) and a capacitor (COUT2). The topology can
