Proposal and Validation of Medium-Frequency Power Transformer Design Methodology
Power electronics is continuously evolving toward higher power densities. Consequently, volume, weight, and material reduction are becoming major design issues, which lead the research focus toward high/medium-frequency power conversion systems. This paper presents a direct and simple design methodology aimed at reaching the best medium-frequency power transformer solution for a given application. Besides maximum power loss or minimum volume requirements, the value of the leakage inductance is adjusted within the design methodology, essential for proper operation of most medium-frequency conversion systems. The proposed design methodology has been applied and experimentally verified on a small scale prototype.
