Abstract
This paper proposed a single-stage interleaved buck-boost-LLC resonant converter to achieve a wide input voltage range up to 8 times of minimum input voltage for railway and medical applications. In this paper,analysis of the proposed converter is performed and presented,including operation principles,gain characteristics,and achievable input voltage range. Zero-voltage switching (ZVS) conditions and the range of switches are also analyzed. Experimental results of a prototype converter with 20-160V input and 12 V/4 A output verifies the analysis and the accuracy of proposed dc gain equations. © 2021 IEEE.
