Abstract: This paper proposes an optimization model for determination of LLC resonant converter design parameters. The optimization model is based on the fundamentalharmonic approximation (FHA) analysis and variable reluctance control method. The objective of the optimal design is to achieve maximum control characteristics by the resonant converter. The reluctance control strategy is used as a converter controller because it offers a wide range of controls compared to switching frequency-based control methods. To verify the optimization results, a precise converter model isimplemented by PSPICE software; The converter model takes into account the parasitic elements of the power semiconductor switches. Simulation results are presented for the resonant converter with optimal parameters. The results obtained from simulations show an acceptable agreement with theatrical analysis.
