N2 - The poor voltage regulation capability of traditional switched-capacitor converters (SCCs) is one severe disadvantage that limits the applicable fields. In this paper, one of the diodes in the five common step-up SCCs - Ladder, Dickson, Fibonacci, Series-parallel, Voltage Doubler- is replaced by a filter inductor. As a result, the new formed switched-capacitor-based (SC-based) hybrid converters attain the wide and continuous voltage regulation capability. Different replaced diode positions lead to different characteristics, so a brief comparison of voltage gain is given. The added inductor may conduct reverse current and thus deteriorate the efficiency, so a boundary map is derived to avoid such region. A hybrid converter based on the 3X Ladder SCC was built to verify the analysis.
