Design of an Experimental Approach for Characterization and Performance Analysis of High-Frequency Transformer Core Materials

High-frequency transformer core materials are used in power converter applications due to high efficiency performance. Their volume and weight can be reduced when higher operating frequencies but at the expense of an increase material losses. Some studies analyzed performance by using finite element method (FEM) analysis, while others experimental model. This study proposes approach compare high-frequency different types. In this way, newly produced rapidly comparing it against a known type, thereby resulting fast identification improved design. empirical makes use standard half-bridge inverter topology enable analysis Actual voltage current measurements determine output throughout specified constant load range switching frequencies. Initially commercial polycrystalline or ferrite E-core were validate characterization jig measured curve trends. The usefulness is then demonstrated comparatively analyzing verifying expected difference between nanocrystalline toroidal materials.
