摘要：A power supply for helix and collector electrodes of a traveling wave tube isdriven by an AC power source having a frequency of at least 500 KHz. The helix supplyincludes plural, stacked voltage doubler AC to DC modules responsive to the 500 KHzsource. The collector supply includes plural AC to DC modules, each having a diode fullwave rectifier bridge, connected in stacked relation. Each of the modules includes atransformer with a ferrite, toroidal core dimensioned so that it is not driven into

saturation by the 500 KHz source. Each module also includes inexpensive, signal switchingdiodes having a recovery time of approximately 4 nanoseconds. The ratio of the collectorto helix DC voltages is maintained constant by threading a common lead through theapertures of the toroidal cores of the helix and collector modules. A separate commonlead threaded through the apertures of the toroidal cores in the collector modules isconnected directly to the 500 KHz power source. A feedback circuit responsive to thehelix-cathode voltage of the TWT controls the helix power supply voltage precisely.
