Abstract
A voltage or current regulated power converter for charging batteries, is described. The power converter comprises an inductor (L), a capacitor cell (C, C), switches (S, S, S, S, S, S, S, S) and a controller. The controller controls the switches such that a commutation cycle of the power converter comprises a first phase, during which the capacitor cell and the inductor are arranged in series and during which a voltage across the serial arrangement of the capacitor cell and the inductor corresponds to V−V; a second phase, during which the capacitor cell and the inductor are arranged in series and during which the voltage across the serial arrangement of the capacitor cell and the inductor corresponds to −V; and a third phase, during which the capacitor cell is floating and during which the voltage across the inductor corresponds to V−Vor to −V.
