Description
Summary:In this paper, an integrated buck and asymmetrical half-bridge (IBAHB) high step-down converter utilizing a single-stage driving design for highly efficient energy conversion is proposed. The proposed converter is able to instantly and synchronously transfer energy from input to output within one conversion period. The advantages of high step-down conversion, lower voltage stress and fewer semiconductor elements verify the feasibility of this proposed topology. The turns ratio of the transformer can be reduced to increase the coupling rate, which decreases the leakage inductance. The proposed integrated topology utilizes the single-stage energy transfer control algorithm to verify that the proposed experimental circuit has a full-load efficiency. This development will achieve the market’s demand for high-buck converters and other related products and the competitive advantage of growing with the trend.
