A DC to DC converter for converting voltage between two voltage levels is described. The converter comprises a plurality of capacitors and switch units and is controllable between a first and second commutation state. In the first commutation state, the converter is configured for connection to higher voltage terminals and the capacitors are connected in series. In the second commutation state, the converter is configured for connection to lower voltage terminals, and the capacitors are connected to form at least two branches connected in parallel, the branches comprising a series connection of at least two capacitors. In some embodiments, one or more intermediate commutation states may also be provided. |
