This paper presents the design of two flat transformers in LLC resonant converter. The trend toward high power density, high efficiency, and low profile in power supplies has exposed a number of limitations in the use of magnetic component structures. In the LLC resonant converter, the switching loss is reduced by soft-switching. Therefore, LLC resonant converter can be operated at high switching...
This paper explores the possibility of applying natural commutation technique to center-tapped HF link inverter. Natural commutation technique has been applied to bridge-type HF link inverter to solve the problems of switching loss and voltage surge across transformer secondary. The condition of natural commutation mechanism in HF link inverter is investigated to enable the design of modified switching...
