PROBLEM TO BE SOLVED: To provide a capacitor accumulator which can charge effectively to a rated voltage each capacitor constituting a device, with little power loss at charging. SOLUTION: This capacitor accumulator is provided with voltage detectors 7 and 8, which detect the voltage across the terminals, provided for each capacitors 5 and 6, series-connected bodies of adjusting capacitors 9 and 10 and electronic switches 11 and 12 which are connected between the terminal of each capacitors 5 and 6, and diodes 13 and 14 which are connected antiparallel to the electronic switches 11 and 12. Then, when the voltage of the capacitors 5 and 6 reach the rated voltage at charge operation, the voltage detectors 7 and 8 send out on-off signals of the electronic switches 11 and 12, and keep the voltage of that capacitor constant. |
