Abstract:
1. A circuit for reducing the energy consumed in driving a capacitive load that is being driven to a controllable voltage level, comprising: one or more first electronic switches connected to the capacitive load for controllably causing the capacitive load to connect to an electronic signal which supplies an adiabatic charging voltage and for charging the capacitive load using the adiabatic charging voltage; one or more second electronic switches connected to the capacitive load for controllably causing only a portion of the capacitive load to connect to an electronic energy storage system and for discharging only a portion of the load using adiabatic discharging; and electronic circuitry that generates control signals for causing the first electronic switches to connect the capacitive load to the electronic signal which supplies the adiabatic charging voltage during a first time period and for causing the second electronic switches to connect the capacitive load to the electronic charge storage system during a second time period.
