Abstract
An operation voltage control circuit device includes a column of selective electrical conduction elements connected in series, a column of capacitors connected in parallel to the selective electrical conduction elements, inverted voltage generation units alternately inserted between the selective electrical conduction elements and the capacitors, and electrode connection terminals connected in parallel to the capacitors between a pair of output terminals and connected to power supply cells connected in series to each other. The column of the selective electrical conduction elements are alternately grouped and are controlled to be alternately switched to an electrical conduction state or a cutoff state. The operation voltage control circuit device further includes auxiliary capacitors connected in parallel to the selective electrical conduction elements excluding both ends of the selective electrical conduction element column, and auxiliary inverted voltage generation units alternately inserted between the selective electrical conduction elements and the auxiliary capacitors.
