This paper presents series-stacked ripple-free resonant dc/dc converter for low voltage fuel-cell applications. By connecting two active voltage doublers in series, the proposed circuit achieved very high-voltage gain. Without using extra input inductors, active-clamped push-pull circuit operating with fixed duty-ratio at 0.5 generate the ripple-free input current; this trait extends the lifetime of the fuel-cell. The active power components are turned on and off with soft switching. A 1-kW prototype of the proposed converter is implemented and tested to verify the theoretical analysis. © 2023 The Korean Institute of Power Electronics.
