Abstract: Disclosed are a resonant switched capacitor direct-current/direct-current converter and a power supply system. The resonant switched capacitor direct-current/direct-current converter comprises N resonant switched capacitor banks, M capacitors and at least one LC series circuit, wherein N is an integer greater than or equal to 2; M is an integer less than or equal to N; each resonant switched capacitor bank comprises a switch and a resonant circuit; the resonant circuit comprises a resonant inductor and a resonant capacitor; and the LC series circuit, i.e. a circuit for connecting an inductor and a capacitor in series, is connected between any two resonant switched capacitor banks. A resonant inductor is not sufficient to completely discharge charges on a junction capacitor of a switch at the moment when the switch is turned off, and therefore, the complete discharging of the charges on the junction capacitor of the switch is realized by means of an added inductor, that is, a current is drained, such that soft switching of the switch is realized. When the soft switching of each switch is actually realized, the power consumption of an entire resonant switched capacitor direct-current/direct-current converter can be reduced, thereby improving the electric energy conversion efficiency of the resonant switched capacitor direct-current/direct-current converter.
