Description

technical field [0001] The invention relates to the technical field of switched capacitor converters, in particular to a step-up resonant switched capacitor converter with a wide voltage regulation range. Background technique [0002] There are five basic topologies for step-up switched capacitor DC converters, namely Ladder, Dickson, series-parallel, Fibonacci, and voltage doubler. After that, a variety of new topologies are derived from the most basic topological structure above. The output gain of the five switched capacitor converters will change accordingly according to the number of circuit stages, but their ideal gains are all integer multiples. For example, the gains of Ladder, Dickson and series-parallel three switched capacitors are 2, 3, 4, 5...n (n is an integer); the ideal gain of Fibonacci switched capacitors is the Fibonacci sequence form, that is, 2, 3, 5, 8...n (n is the sum of the first two digits); the ideal gain of the voltage doubler is 2, 4, 8, 16...n...
