Resonant-recovery power reduction techniques for pulse generation
Abstract:
The disclosed embodiments provide a circuit for driving a capacitive load. The circuit includes a first inductor with an input terminal and a load terminal, wherein the load terminal is coupled to the capacitive load. The circuit also includes four or more switching devices. The switching devices may hold a voltage on the load terminal at zero volts. Next, the switching devices may charge the capacitive load through the first inductor until the voltage on the load terminal reaches a first input voltage supplied by a voltage source. The switching devices may then hold the voltage on the load terminal at the first input voltage. Finally, the switching devices may discharge the capacitive load through the first inductor until the voltage on the load terminal reaches zero volts.
