Power converter with modular stages connected by floating terminals
First Claim
1. An apparatus comprising a power converter, said power converter comprising first and second switches, and a set of switching elements for connection to capacitors to form a switched-capacitor network that has first and second terminals, wherein said first and second terminals are at different voltages,wherein said first switch connects to said first terminal and to an inductor, andwherein said second switch connects to said inductor and to said first switch,wherein said first and second switches are configured such that when said first switch is closed and said second switch is open, current through said inductor increases, and when said first switch is open and said second switch is closed, current through said inductor decreases, andwherein said switched-capacitor network forms first and second paths that extend between said first and second terminals when said set is in corresponding first and second states.

Abstract
An apparatus for electric power conversion includes a converter having a regulating circuit and switching network. The regulating circuit has magnetic storage elements, and switches connected to the magnetic storage elements and controllable to switch between switching configurations. The regulating circuit maintains an average DC current through a magnetic storage element. The switching network includes charge storage elements connected to switches that are controllable to switch between plural switch configurations. In one configuration, the switches forms an arrangement of charge storage elements in which at least one charge storage element is charged using the magnetic storage element through the network input or output port. In another, the switches form an arrangement of charge storage elements in which an element discharges using the magnetic storage element through one of the input port and output port of the switching network.
