Claim Text:
1. A method for regulating voltages in an electronic device, the method comprising: balancing, by a circuit, a selected capacitor comprised in a plurality of capacitors by performing an operation from the group consisting of (i) injecting energy from an energy storage element into the selected capacitor and (ii) extracting energy from the selected capacitor and storing the extracted energy into the energy storage element; selecting, by the circuit, the operation based on a voltage across the selected capacitor and an average voltage, the average voltage being an average of voltages across capacitors of a set of capacitors from the plurality of capacitors; and regulating, by the circuit, a current of the energy storage element by periodically monitoring the current and applying a voltage across a combination of capacitors from among the plurality of capacitors to the energy storage element based on a comparison of the current with a threshold current.
