Abstract
A switched capacitor voltage converter includes an inductive branch and two branches, by controlling a turning on and off of switch transistors, charges on a parasitic capacitor of one branch are completely transferred to another branch of the two branches via the inductive branch within a period of time after primary switch transistors are turned off, and voltage difference between both terminals of each of the primary switch transistors become zero, and then the primary switch transistors are started to be turned on, the respective voltage differences of the primary switch transistors are zero at a moment when the primary switch transistors are turned on.
