Abstract: For decades, the technology and engineering domains have been constantly demanding high-performance magnetic materials. Recently, polymer bonded NiZn ferrite magnetic materials mixed with titanium (IV) isopropoxide (C₁₂H₂₈O₄Ti) for power converter applications have been found to be very promising in reducing the loss, cost, and material weight when compared to their conventional counterparts using air-core technology, conventional soft ferrites, and powder iron. The proposed magnetic core is flexible in both size and shape and is not brittle. The design of a high-frequency transformer for a 100 W two-transistor forward converter-based electric vehicle battery charger operating at a switching frequency of 360 kHz is reported in this paper. Printed circuit board prototyping and experimental results as well as comparisons with conventional converters are provided to validate the application feasibility of the proposed materials.
