Design for better thermal management in high-power high-frequency transformers

The paper discusses a new approach to the design of thermal management for high-frequency high-power transformers. It is based on heat removal by conduction. Advanced heat conducting elements like heat-pipes are implemented. The heat is collected on dedicated surfaces called thermal surfaces where the heat exchange with the environment occurs. The proposed heat removal concept is discussed, the process used to design the system and evaluate the proposed concept is described including used models and the paper is concluded by discussing the case study and the practical results.
