Abstract
A control circuit for a power supply for at least one Traveling Wave Tube (TWT) that uses the cathode voltage as a reference point allowing independent, variable control of each TWT. The cathode current is varied by varying the anode voltage. Therefore, it is not necessary to operate the TWT below maximum power at full cathode current. The result is improved operating efficiency for the TWT. A single power supply is capable of powering several TWT's resulting in a significant weight and cost savings for space applications.
