Abstract
A switched capacitor converter circuit includes: plural capacitors and plural switches which periodically switch the coupling relationships of the plural capacitors. During a first period, the switches control at least two of the capacitors to be electrically connected in series between the first power and the second power, and control a first capacitor of the capacitors to be electrically connected in parallel to the second power. During a second period, the switches control at least two of the capacitors to be electrically connected in series between the second power and a ground voltage level, and control a second capacitor of the capacitors to be electrically connected in parallel with the second power, thereby executing power conversion between the first power and the second power.
