Abstract
There is disclosed an electrical storage capacitor system that performs initializing charging and storage charging for energy storage with reduced energy loss. The capacitor system comprises capacitors connected in series, comparators for comparing the voltages developed across the capacitors with a first reference value, voltage limitation means connected in parallel with the capacitors to limit the voltages of the capacitors to a second reference value during initializing charging, and a charger. During initializing charging, the capacitors are charged while operating the voltage limitation means. Storage charging for energy storage is done according to the output signals from the comparators until the voltage of any one of the capacitors reaches the first reference value.
