The conventional IM transformer given in is The transformer and output inductor are located on the center leg and Shows the proposed IM transformer and the circuit connection in the output The center-tapped transformerĪnd the output inductor are usually integrated in one EE or EI core. ZVS PSFB converter and the performance is discussed. An E-coreĮxperimentally compared with the conventional one through a 1.2kW prototype Proposed IM transformer is analyzed electrically and magnetically.
TRANSFORMER EN VIVO SERIES
The transformer winding is located on the center leg for close magneticĬoupling and the inductor is wound on two outer legs in series connection. Since the transformer coupling is low, EMI may beĪ new IM transformer is proposed for ZVS PSFB converter in this paper. Much higher than one in center leg because the center leg has nearly two timeĬross-sectional area of the outer leg. Inductor flux only flows in the center leg. Transformer and a half of the DC flux of inductor flows in outer legs but the Transformer winding is typically located on the two outer legs in seriesĬonnection and the inductor is wound on the center leg. In some case, overallĮfficiency may be increased and an EMI problem may be reduced.įor a PSFB converter, several IM transformers are proposed. So that the size and power density can be improved. The magnetic parts in the converter may be reduced, Magnetic components are integrated in one magnetic structure. The IM transformers begin to be used in the low output voltage and highĬurrent power electronics system. Transformer, the power density can be largely increased. Size of proposed IM is reduced up to 20%. The efficiency of proposed IM is similar to the one of conventional IM but the The proposed IM transformer is compared with conventional IM transformer. The applications of these circuit are verified on aġ.2kW prototype converter through experimental results. The analysis of each timing interval is included for ZVS.
The design equations and equivalent magnetic circuit are presented. Located on the center leg the output inductor is located on the outer legs withĪir gaps. In this dissertation a new IM transformer is proposed. That can be applied to high frequency converter. Performances, like power density, packaging, size and cost of IM transformer The purpose of this design is to improve the The design of IM transformer is considered in a zero voltage switching (ZVS) Integrated magnetic (IM) has been widely used in power electronics system. In partial fulfillment of the requirements Integrated Magnetic Transformer for ZVS PhaseĪ Dissertation submitted to the Faculty of the Graduate School
