Abstract:
An electrical storage capacitor system for charging plural capacitors connected in series, said electrical storage capacitor system comprising:first voltage detection means for sensing that voltages developed across said capacitors are coincident with a first reference voltage;second voltage detection means for sensing that voltages developed across said capacitors are coincident with a second reference voltage;current bypass means for bypassing a part of the charging current around said capacitors according to outputs from said second voltage detection means;initializing charging means for performing initializing charging while causing said second voltage detection means and said current bypass means to control said capacitors; andstorage charging means for charging said capacitors connected in series to store electric energy in said capacitors, said storage charging means performing storage charging for energy storage according to output signals from said voltage detection means until the voltage of any one of said capacitors reaches said first reference voltage.
