A topology-reconfigurable cascaded resonant DC-DC converter with inherent voltage balance capability for wide range applications is proposed in this paper. The cascaded connection of DC-DC converter can increase the voltage and current handling capability, while this topology faces voltage and current balance issues caused by the parameters mismatch. To address the above-mentioned issues, a topology based on cascaded connection of resonant DC-DC converter with inherent voltage balance capability is presented. The proposed topology is based on cascaded connection of resonant DC-DC converter, which ensure the input voltage sharing through charging and discharging the inherent flying capacitor. Furthermore, a reconfigurable parallel-series structure on the secondary side is devised to expand the operational range. The characteristics of the proposed converter are analyzed, which reveals the segmental voltage gain property of the proposed topology. Moreover, the analysis of the voltage balance mechanism confirms the converter’s robustness in achieving and maintaining voltage balance. Finally, a 400 W experimental prototype is built and tested to verify the effectiveness of the proposed topology. The experimental results are presented to confirm the feasibility and viability of the proposed converter.
