The power supply for high-tension switch of traveling-wave tube is an important part of the power amplifier of communication satellite and radar transmitter.It is designed for military use,and widely used in the fields of communication,electronic countermeasure,etc.There are extremely strict technical specifications for the power supply which is used in airborne radar,such as reliability,dimension,weight,efficiency and so on,but what we have done satisfies all demands.

The typical demands for this sort of power supply as follows:

1,A set of the power supply consisits of three groups:output voltage,voltage regulation and rated current.The specifications as follows:

UA:+3200V ±200V 0.5mA

UH:+4150V ±200V 5mA

UC:+3200V ±200V 80mA

2,The power input for all the three voltage regulators is DC24V±1V.

3,Both the voltage stability and load stability of UA,UH,UC are ±0.1%,ripple(p-p)0.1%

4,Input and output share ground.The ground wire of output must be grounded before     working.

5,It can be working continuously for a long time.

6,Work temperature:-40 ~ +70.
