Since there is only one working mode of continuous wave or pulse after the design of a traditional spaceborne travelling wave tube(TWT) amplifier is finished and the output power at the saturated working point is fixed,a novel design scheme for space TWT power supply is proposed,which is compatible with multiple working modes including continuous wave and pulse. The TWT power supply and multi-mode TWT designed through this scheme are integrated into a multi-mode TWT amplifier,which have functions of continuous wave mode,low repetition rate pulse mode,high repetition rate pulse mode and adjustable on-orbit power. As a result,it can be applied to communication,navigation,data transmission and remote sensing observation satellites,thus making the on-orbit reconfigurable load possible. Through a simulation test,it is found that the power efficiency of the multi-mode space TWT reaches 94％,the repetition frequency range covers the continuous wave up to 10 kHz,and the adjustable output power ranges between 47 and 53 dBm.
