Abstract
A method for controlling a switching power converter which includes a central capacitor exchanges charge between the capacitor and plural nodes of a first terminal, and then transfers the charge between the capacitor and plural nodes of a second terminal. The charge interchanged between the capacitor and the nodes establishes the amount of power transferred during each cycle. The charge which is interchanged is controlled by selecting the electrical phase between the currents drawn from the nodes and the voltages at the nodes.
