高調波解析技術に基づく絶縁型Φ₂級DC-DCコンバータの設計

抄録

The isolated class-Φ₂ DC-DC converter has attracted attention as a circuit topology that achieves high efficiency. However, there are no reported analysis methods and design techniques for isolated class-Φ₂ DC-DC converters. In this study, the harmonic analysis technique is applied to the isolated class-Φ₂ DC-DC converter, which enables circuit analysis with arbitrary duty ratio. In addition, design curves are obtained using this harmonic analysis, and design examples are presented. The loss analysis of the manufactured isolated class-Φ₂ DC-DC converter was performed to clarify the ratio of copper losses generated by the magnetic components.
