<p>A multilevel power supply comprises two power sources V1, V2 that share a common node, a switching arrangement Q1, Q2, a charge storage device, e.g. capacitor C1, and a first stage output terminal V5. The two power sources are configured to provide a first potential V1, a second potential V2 and a third potential V3, wherein V1 > V2 > V3. The switching arrangement is configured to charge the charge storage device between potentials V1 and V3 in a first switching state and to connect the charge storage device between potential V2 and the output in a second switching state. The switching arrangement may also be configured to connect the output to potential V2 in a third switching state and/or to potential V1 or V3 in a fourth switching state. A second charge storage device may be provided that can be connected between the first stage output and a second stage output in a fifth switching state.</p> |
