Abstract
A connection-switched capacitor storage system comprises plural capacitors, parallel monitors connected with the capacitors, respectively, switches for switching the connections of the capacitors from a series combination to a parallel combination or vice versa, and a control portion. The parallel monitors bypass the charging current for the capacitors when the terminal voltages of the capacitors exceed a given voltage, thus limiting increases of the terminal voltages of initializing the terminal voltages of the capacitors to their original level. The control portion controls initialization and switching of the connections of the capacitors. The control portion causes the parallel monitors to initialize the capacitors near the voltage at which the connections of the capacitors are switched by the switches.
