Patent ID: 8305052

Claim:
A method of supplying bursts of substantially constant voltage to a plurality of pulse loads, the method comprising: providing an array of low voltage current sources, each for feeding constant DC (Direct Current) current at a nominal voltage to a respective storage capacitor, each of which is coupled to a plurality of switch power supplies; coupling each of the switch power supplies to a respective output storage capacitor for feeding voltage to the pulse load; storing energy in each of the storage capacitors during both active and inactive portions of a load switching cycle of the respective switch power supply, to which the corresponding storage capacitor is coupled, for feeding voltage to the respective pulse loads during an active portion of the load switching cycle; and supplying the energy, stored in the respective storage capacitor to the respective switch power supply, to which the storage capacitor is coupled, and then to each of the pulse loads during the active portion of the load switching cycle, wherein the supplying of said energy comprises computing an average current that should be fed to the respective storage capacitor in order to ensure that sufficient energy will be stored in said respective storage capacitor to feed the pulse load without substantially completely draining said respective storage capacitor.
