Abstract
A system and corresponding method, including a battery including a plurality of battery modules arranged in series, each module including a switch and a diode arranged in series and connected in parallel to the module. The system further includes a capacitor connected directly by an electrical connection to a point situated between the diode and the switch of each module, and directly to the negative terminal of the battery, and a load connected in parallel to the capacitor, a mechanism controlling each module switch using a pulse width modulation signal having a duty cycle that varies between 0% and 100%.
