The ripple of the cathode high voltage power supply is the key factor that influences the transmitter frequency spectrum.Aiming at the application environment of the airdrop type of radar,which includes the strong impact,the low atmospheric pressure and the limited installation environment,this paper proposes a design method of the cathode high voltage power supply for the airdrop type radar transmitter.It adopts the soft switching resonance technology to reduce the loss of the power switching tube,provides the output high voltage by the series cascade multiple voltage circuit,takes effective means to reduce the ripple of the output high voltage,and improves the reliability of the system.This method has good adaptability in the working environment that includes the strong impact and the low atmospheric pressure.This cathode high voltage power supply has good miniaturization effect,big power densities,and good adaptability to the transmitter's working ratio.It is propitious to the transmitter system,which improves its power capacity,working efficiency and quality of the transmitter frequency spectrum.It provides new ideas for the development of the transmitter high voltage power supply and has good application prospects.
