The design of magnetics plays a vital role in achieving the essential requirements of switching regulator circuits such as high-power density level, low thermal dissipation and high efficiency. Hence, this paper is focused on the high-frequency practical transformer design for flyback topology that is most widely used in the switched mode power supplies units. A case study is performed by employing different core configuration for high frequency flyback transformer which is the main contribution of this paper. The comparative performance analysis in terms of the dimensions, losses incurred and efficiency is reported for selecting the proper choice of core for the flyback topology. © 2023 IEEE.Coupled InductorFerrite Core MaterialFlyback ConvertersTransformer Design
