N2 - Five common step-up switched-capacitor converter (SCC) topologies - Ladder, Dickson, Fibonacci, Series-parallel, Voltage Doubler- have limited voltage regulation ranges, and the maximum voltage gains are predetermined by the circuit configurations. In this paper, one active switch in the five common SCCs is replaced by a filter inductor to form a family of hybrid step-up DC-DC converters. Compared with the traditional SCCs, the new hybrid converters feature wide voltage regulation range and high step-up gain, which is determined by both circuit configuration and duty cycle. A hybrid converter based on 3X Ladder SCC was built and tested to verify the analysis.
