Abstract
A circuit for driving capacitive loads which utilizes the temporary storage characteristics of an inductor in a resonant LC configuration to force current to flow from a low potential location to a high potential location at selected switching times. The circuit is controlled by an externally activated switching network in series with the inductor and capacitive load which network comprises two unidirectional conducting branches oriented to allow current flow in opposite directions through the respective branches. By appropriately opening and closing switches in the two branches, the switching network can regulate the flow of current through the inductor to either charge or discharge the capacitive load without the necessity of dissipating energy when the capacitive load is either charged or discharged. Components are also included for replacing the inherent power losses of the circuit.
