A Proposed System for Magnetic Characteristics Determination of Ferrite Core

This research deals with the determination of the magnetic characteristics of a ferrite core in certain frequency in lab. Two proposed power supplies are used for this purpose. The first is a push-pull circuit used for that purpose. The push-pull circuit intended due to its ability to work as an inverter, and to isolate the measuring circuit. Also, another circuit composed of a single phase, self-tuned H-bridge inverter is used for the same purpose. The validity of the proposed circuits is studied and implemented. The frequency range of the measurements is limited to be suitable for power electronics converters and induction heating applications. A practical application approves the validity of the proposed circuits for different applied voltages and frequencies. The designed measuring circuits simplify the design process of high-frequency ferrite transformers and coils.
