Abstract: The invention relates to a resonant switched capacitor direct current voltage converter which comprises a first voltage node, a second voltage node, a first switch, a second switch, a first diode, a second diode and a control circuit, wherein a first voltage exists between the first voltage node and a negative wire; a second voltage exists between the second voltage node and the negative wire; and the control circuit provides switching gate signals for the first and the second switches. The resonant switched capacitor direct current voltage converter further comprises a center-tapped inductor and a resonant capacitor, wherein the center-tapped inductor is connected between the first switch and the second switch; and the resonant capacitor is connected between the common node of the first and the second diodes and the central node of the center-tapped inductor. Compared with the conventional switched capacitor direct current voltage converter, the invention has the advantages of reducing complexity, loss and cost, improving the speed, and avoiding the limitation.
