摘要
A topology morphing multi-element resonant converter (MRC) is proposed in this paper. The converter introduces two auxiliary switches and is able to exchange its equivalent topology flexibly. Consequently, widely adjustable voltage gain from 0 to 8 is acquired within a small operating frequency range, which contributes to highly efficient conversion as well. The resonant parameters of the converter are also designed and tested by a prototype. The experimental results demonstrate that the converter harvests relatively high efficiencies among the entire input voltage variations from 25V to 300V, and the highest efficiency point has reached 98.1%.
