Abstract For the conventional PWM converters, the smaller dead time, the higher efficiency, but the resonant converters are not so. Based on DC transformer(DCT) of the LLC resonant topology, this paper proposes a design for resonance parameters based on optimal solution between the dead time and magnetizing inductance. Through the selection of the dead time and magnetizing inductance, it can obtain the optimum efficiency. At the same time, according to the characteristics of LLC-DCT, the selection of the ratio of magnetizing inductance to resonant inductance and the quality factor are discussed. Finally, a 150W the LLC-DCT prototype is designed on mentioned approach. The experimental results show the effectiveness and accuracy of the design method.

Key words： LLC-DCT optimal solution for dead time optimum efficiency immediate bus converter
