1. Power supply apparatus for operating a controlled device with a sequence of momentary current pulses, comprising:

  • an energy converter connected via a first node to an energy storage device, said energy converter being capable of converting energy at varying voltage levels from the energy storage device to energy at a constant output voltage on a second node; and

    an energy storage capacitor connected to the second node and connected via a switch controller to the controlled device, said switch controller being responsive to signals from a logic controller, which is connected to the second node, to discharge pulses of energy from the energy storage capacitor to the controlled device.
