Research Focus: Developing design methodology for high-frequency transformer using multi-objective optimization • Constructed a high-frequency core-type transformer to include in an isolated unidirectional DC-DC converter, while adhering to insulation requirements. • Performed characterization of the high-frequency transformer using experimental procedures. • Established computationally efficient method to perform magnetic analysis of a core-type high-frequency transformer. This enabled accurate estimation of transformer leakage inductance and normalized flux densities in the windings. Validated the magnetic analysis using Finite Element Analysis and experimental results. • Simplified the time domain simulation of a candidate DC-DC converter to estimate the high frequency harmonics in the transformer currents necessary for loss calculations. • Surveyed analytical methods to calculate the parasitic capacitance in high frequency magnetic components. • Investigated the common mode conduction in the high-frequency transformer and its mitigation by using Faraday shield.
