Embodiment Construction

[0022] see figure 1 As shown, the present invention is a tubular nanosecond-level high-voltage steep pulse source, which is composed of a high-voltage DC source, an input connector 1 , a pulse transmission path 2 , an operation switch 3 and an output connector 4 .

[0023] The schematic diagram of the high voltage DC source is shown in figure 2 shown. The high-voltage DC source uses a flyback switching power supply, which uses a high-frequency switch to switch a low-voltage DC source to convert the DC signal into a high-frequency signal, and converts the low-voltage high-frequency signal into a high-voltage high-frequency signal through a high-frequency step-up transformer, and finally through the rectifier The circuit converts an AC high voltage signal to a high voltage DC signal. The maximum output of the power supply is 2kV, the load is 2MΩ, and the maximum output power is 2W.

[0024] The input connector 1 is composed of an input high-voltage BNC connector 11 and an in...

Abstract

The invention discloses a tube-type nanosecond high voltage steep pulse source, which comprises a high-voltage DC source, an input connector, a pulse transmission path, an operation switch and an output connector, wherein the input connector is composed of an input high voltage BNC joint and an input joint, the input high voltage BNC joint is connected with the high-voltage DC source, the output connector is composed of an output joint and an output high voltage BNC joint, the pulse transmission path is connected with the input joint and the output joint, the operation switch is arranged outside the pulse transmission path, and the pulse transmission path is provided with a wet reed tube for controlling output of the high voltage steep pulse source through control of the operation switch. The steep pulse source of the invention has a small size, is light in weight and can be used in a test device for measuring space charges by using a pulsed electroacoustic method; and as the wet reed tube is adopted for replacing a spark gap, the weight of the power supply is greatly reduced, and through test, nanosecond pulse voltage with a pulse width about 1ns and the highest amplitude of 2000V can be outputted.
