Abstract:
An improved optimal control strategy of full bridge LLC resonant converter under wide input is proposed by analyzing the state trajectories under three operational modes. The influence of circuit parameters on the applicability of the control strategy is discussed in details. The simulation results verified the feasibility of the proposed control strategy.
Keywords:full bridge LLC resonant converter  wide range input  optimal trajectory
