Abstract In this paper, we study on a novel Buck-Boost converter of high efficiency by soft switching method. The proposed Buck-Boost converter is applied to new soft switching method in restraint of increment of switching power loss in the conventional Buck-Boost converter. The soft switching circuit is designed to modification of a energy storage inductor and a snubber circuit used by the conventional converter, and then the proposed converter is simplified. The controlling switches of the proposed converter is operated with soft switching by a partial resonance behavior. The output voltage of the converter is regulated by PWM control technique. The discontinuous mode action of current flowing into inductor makes to simplify control method and control components. The proposed Buck-Boost converter is compared with the conventional converter. Some computer simulative results and experimental results are confirmed to the validity of the analytical results.
