Abstract
A high-conversion-efficiency reconfigurable series-parallel switched-capacitor voltage converter includes N−1 control units and is capable of realizing a voltage conversion ratio in a range from 1:1 to N:1 between a second conversion terminal and a first conversion terminal. When the voltage conversion ratio between the first conversion terminal and the second conversion terminal of the reconfigurable series-parallel switched-capacitor voltage converter is Nx:1, the N−1 control units are divided into k+1 control modules. k control switch tubes are configured to respectively correspond to the preceding k control modules. Each one of the preceding k control modules comprises m control units, and the last control module comprises t control units; m=Nx−1; k and t satisfy N−1=m×k+t; k and m are both 0 or are both positive integers; and t is as small as possible.
