ABSTRACT:
A storage capacitor power supply has a plurality of electric double layer capacitors connected in series. Each capacitor has connected in parallel therewith a charge-limiting circuit. Each charge-limiting circuit measures a voltage across its corresponding capacitor and causes a charging current to bypass the capacitor when it is charged to a value corresponding to a reference voltage established by the charge-limiting circuit. When all the capacitors are charged to their corresponding reference voltages, the charging current is terminated whereafter the capacitors are discharged with a discharge current. When the capacitors are charged with a recharging current from a partially discharged state, the capacitors are charged to values corresponding to their respective reference voltages at the same time without bypassing the recharging current around one or more of the capacitors.
