A mixed switched-capacitor cell is proposed by integrating a voltage divider with a voltage multiplier. It is inserted in a boost stage for achieving a converter with high conversion ratio, low voltage stress on switches, non-pulsating input current as required as front-end to electrical grids supplied by renewable energy sources. The generalization of the proposed cell allows to achieve an ultra-high dc conversion ratio. Analysis and experimental data show the superiority of the proposed converter over other hybrid converters with similar complexity: higher dc voltage gain and less voltage stress on the switches.
