Abstract

A multiple cell capacitor (200) includes at least first and second capacitor cells (260) and a cell balancing circuit (265) electrically coupled to the first and second capacitor cells (260). Packaging material (280) encloses the first and second capacitor cells (260) and the cell balancing circuit (265). The cell balancing circuit (265) can include, for each capacitor cell (260), a resistor (265) formed electrically in parallel with that capacitor cell (260).
