Abstract
A series-parallel switched capacitor voltage converter includes inductive branch, a first branch and a second branch, the inductive branch is connected between the first branch and the second branch. By controlling turning on and off of the switches of the first branch, the second branch and inductive branch, charges on capacitors of one branch are completely transferred to another branch via the inductive branch within a period of time after all main switches of the first branch and the second branch are turned off, and a voltage difference between both terminals of each of the main switches becomes zero, then each of the main switches is started to be turned on, the voltage difference of each of the main switches is zero at an instant when the main switches are turned on.
