Abstract
A device, such as a pump capacitor or an energy storing inductor, is charged by coupling it to a voltage source. Thereafter, the device is connected in parallel to one of the capacitors or capacitance cells to be charged, and the charging of the device and successive connections of it in parallel to a selected capacitor of the series of capacitors for charging it are replicated for all the capacitors of the series. The sequence of different connections of the device to the charge voltage source and to the selected one of the capacitors of the series is actuated through a plurality of coordinately controlled switches that establish distinct current circulation paths, according to a switched-capacitor or switched inductor techniques driven by respective periodic control signals that may be generated from a master clock signal.
