This paper presents the integrated magnetic circuit desgning method for phase shift full bridge(PSFB) converter. The integrated magnetic circuit is implemented on redesigned of EI core. The transformer windings are located on center leg and the two inductors are located on the outer legs with air gap. Based on the equivalent circuit model, the principle of operation of the PSFB converter is explained. The operation and performance of the proposed circuit are verified on a 1.2 ㎾ prototype converter. The analysis and design of the integrated magnetic circuit is verified through the experimental and simulation results.
