As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...

A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

Significant cost reductions and performance enhancements in planar magnetics have been introduced in recent years. These include replacing costly multilayer PCBs with lower-resistance flat coil ...
