Electrical storage element

Claim 1

A four-phase electrical dynamic storage element comprising: two controllable components controllable into a conducting or cut-off state in phase opposition; a pair of storage capacitances, each of said storage capacitances lying in parallel with the control path of a different one of said two controllable components and controlling the state of its associated controllable component, a separate charging and a separate discharging circuit for each said capacitance, the discharging circuit of each capacitance consisting of the series connection of the current path of the controllable component associated with the other of said pair of capacitances and the current path of a further controllable component which forms a gate, and the charging circuit of each capacitance consisting of a further gate whose current path is connected in series with the discharging circuit of the associated capacitance; generator means for supplying cyclically repeated four-phase clock pulses separately to the control inputs of said gates for causing charging of both said storage capacitances and thereafter discharging of one of said storage capacitances depending on its previous state of charge; and means connecting each gate disposed in the charging circuit of a capacitance with an output of said generator means so that the respective clock pulses which control the gate in the charging circuit are fed to the associated capacitance via said charging circuit gate as the charging voltage.
