A system comprising:
- a first switched-capacitor converter including a plurality of switches connected in series;
- a second switched-capacitor converter;
- and
- a third switched-capacitor converter connected in parallel with the second switched-capacitor converter between a common node of two switches of the plurality of switches and a load, the second switched-capacitor converter and the third switched-capacitor converter both including inductors.
1 more element
A system comprising:
- a plurality of switched-capacitor power conversion stages connected in cascade between a power source and a load, a first switched-capacitor power conversion stage of the plurality of switched-capacitor power conversion stages directly connected to the load, the first switched-capacitor power conversion stage including a plurality of first switched-capacitor power converters connected in parallel, each of which including an inductor, wherein a second switched-capacitor power conversion stage of the plurality of switched-capacitor power conversion stages is connected to the first switched-capacitor power conversion stage, the second switched-capacitor power conversion stage including a plurality of second switched-capacitor power converters, each of which connected to inputs of two parallel-connected first switched-capacitor power converters.
A method comprising:
- configuring a first switched-capacitor converter to operate at a first duty cycle;
- and
- configuring a second switched-capacitor converter and a third switched-capacitor converter to operate at a second duty cycle, wherein the second switched-capacitor converter and the third switched-capacitor converter are connected in parallel and operate at 180 degrees out of phase from one another.
