ABSTRACT:
Apparatus for repeatedly generating a staircase ramp voltage pulse on a bus connected to a capacitive load employing a set of DC voltage sources, each producing a voltage of a step in the staircase ramp voltage. A storage capacitor is connected between the output terminal of each voltage source and ground. An FET switch is connected between each of the output terminals and the bus and between ground and the bus. A timing circuit closes each of the FET switches in order to produce a staircase ramp voltage on the bus charging the capacitive load. When it is desired to discharge the capacitive load, the timing circuit then closes the switches in reverse order. Each storage capacitor is charged by the discharging capacitive load to a voltage above the voltage of its associated voltage source. The energy thus stored is used during the next cycle to contribute to the energy required to charge the capacitive load on the bus.
