Abstract
A switched capacitor voltage converter includes an inductor and a plurality of switch transistors between two branches of a conventional parallel switched capacitor voltage converter, by controlling a turning on and off of the plurality of switch transistors, electric charges on a parasitic capacitor of a first branch are completely transferred to a second branch via the inductor within a period of time when all primary switch transistors are turned off, so that a voltage difference between both terminals of each of the primary switch transistors becomes zero, then the each of the primary switch transistors is turned on, the voltage difference between both terminals of the each of the primary switch transistors becomes zero at an instant when the each of primary switch transistors is turned on respectively, therefore a switching loss of the plurality of switch transistors is reduced and a conversion efficiency is improved.
