- Abstract
- This paper describes the research conducted on the design method of HFT (High Frequency Transformer) in high frequency application. The proposed design method accurately predicts inductance based on magnetic equivalent model considering MPL (Magnetic Path Length) and Fringing effect. Here, the multi-objective optimization technique is applied to optimize the HFT design. The effectiveness of the proposed method is verified through an experiment of a 500W LLC resonant converter. © 2023 The Korean Institute of Power Electronics.
