FIELD: electricity.
SUBSTANCE: invention is referred to power control system for power control system for travelling-wave tube double amplifier and may be used in telecommunications satellites. In particular the power control system for travelling-wave tube double amplifier comprises at least two travelling-wave tubes (10, 24), each of them containing one zero anode electrode (13), electronic power converter, power control unit coupled to each travelling-wave tube (10, 24) and configure for setting zero anode electrode (13) to a certain minimum value when stand-by mode is actuated, at that power control unit maintains operating power of the travelling-wave tube (10,24) at value below its rated operating value.
EFFECT: maintenance of operating power for the travelling-wave tube in stand-by mode below its rated operating range.
