Abstract: A resonant switched capacitor converter includes a control system, a first capacitor, a plurality of resonant systems, and a plurality of second capacitors coupled in series. The first capacitor is coupled in series to the second capacitors. One resonant system corresponds to one second capacitor. Each of the resonant systems includes a first switch system, a resonant circuit, and a second switch system. The control system is coupled to the resonant systems and configured to control, based on a target output voltage gain, switches in the first switch system and the second switch system in each resonant system to be turned on or turned off, to enable the resonant switched capacitor converter to obtain an output voltage gain equal to the target output voltage gain.
