ABSTRACT:
An electronic device for transferring charge includes: a charge storage device; an inductive section; and a switching array having a first set of switches connected to a first node of a power terminal, a second set of switches connected to a second node, and a third set of switches connected to a third node. The device includes a controller configured to control the switching array so as to cause a first predetermined charge to interchange between the first node and the charge storage device, a second predetermined charge to interchange between the second node and the charge storage device, and a third predetermined charge to interchange between the third node and the charge storage device; and a bypass switch configured to close a circuit between the charge storage device and the inductive section so as to prevent charge from interchanging between the charge storage device and the nodes.
