PROBLEM TO BE SOLVED: To uniformly charge a plurality of electric double-layer capacitors connected in series or in parallel with each other, without balance resistors. SOLUTION: Entire electric double-layer capacitors 10-1 to 10-n are charged by a DC power source 26. A common rectangular wave is input from a pulse power source 12 to DC reproducing circuits 14-1 to 14-n, in parallel with the charging of the capacitors, and DC-restored to charge the capacitors 10-1 to 10-n. Since the circuits 14-1 to 14-n operate to make the charging voltages of the capacitors 10-1 to 10-n converge to the rectangular double-amplitude voltage, double-amplitude voltage is set to the rate voltage, and thereby the charging voltages of all the capacitors 10-1 to 10-n can be converted to the rated voltage.
