摘要： A system and method for efficiently charging and discharging a capacitive load from a single voltage source. The system includes a first switch for selectively connecting the voltage source to the load and a second switch for selectively providing a short across the load as may be common in the art. A particularly novel aspect of the invention resides in the provision of plural capacitive elements and a switching mechanism for selectively connecting each of the capacitive elements to the load whereby the load is gradually charged or discharged. In the illustrative embodiment, the switching mechanism includes a set of switches for selectively connecting each of the capacitive elements to the capacitive load and a switch control mechanism for selectively activating the switches.

摘要： A system and method for reducing reflections in a transmission line and for recovering energy from the load in the transmission during the process. At least three drive signal levels are utilized. The transition from the second level to the third level during a rising transition and the transition from the second level to the first level during a falling transition is timed to coincide with the arrival of the reflected signal from the immediately-preceding transition. A capacitor is advantageously used as the source for the intermediate drive signal levels and advantageously facilitates energy recovery and conservation.

摘要： Power-efficient, pulsed driving of capacitive loads to controllable voltage levels, with particular applicability to LCDs. Energy stored in a portion of the capacitive load is recovered during a recovery phase. Time-varying signals are used to drive the load and to recover the stored energy, thus minimizing power losses, using processes named adiabatic charging and adiabatic discharging.

摘要： A power source, inductor and clamping device coupled to generate substantially sinusoidal drive pulses. The power source has an output capacitance. The inductor is connected to the power source and to the load to be driven. In combination with the inductor, the output capacitance of the power source and the input capacitance of the load to be driven create a resonant circuit which generates a stream of substantially sinusoidal pulses. A clamping device is connected to the inductor and prevents the stream of pulses which are driving the load from exceeding a clamping level. In one preferred embodiment, a complementary set of clamping devices and inductors are used to generate a complementary set of pulse streams.
