Abstract

The invention relates to a 32KV electron gun pulse modulation power supply and relates to the field of electron gun pulse modulation. The purpose of the invention is to solve a problem that a traditional electronic gun modulation power supply is large in size, not continuously adjustable in a wide range, and low in efficiency. The modulation power supply comprises a pre-stage modulation power supply, a modulator, a pulse transformer and a controller. The voltage signal output end of the pre-stage modulation power supply is connected with the voltage signal input end of the modulator and the voltage signal input end of the controller. The control signal output end of the controller is connected with the control signal input end of the modulator. The modulation signal output end of the modulator is connected with the modulation signal input end of the pulse transformer. The pulse transformer outputs pulse high voltage. The voltage obtained by the pre-modulated power supply is converted into the pulse high voltage through the switching of and off of the modulator and the pulse transformer. The 32KV electron gun pulse modulation power supply adopts a full-bridge phase shifting mode to realize the ZVS of a power tube, thereby reducing the switching loss and achieving efficiency up to over 90%.

Description

technical field [0001] The invention relates to the field of electron gun pulse modulation. Background technique [0002] The electron gun is a device that uses the photoelectric effect and uses high-power microwaves to establish a strong electric field in the resonant cavity to accelerate the electrons emitted by the hot cathode located in the resonant cavity, so that the electrons can quickly reach the relativistic speed. It needs to have: 1. An accelerating voltage of tens of kilovolts or more ensures the energy of the electric field. 2. Can give enough pulse power. [0003] At present, some electron gun pulse modulation power supplies can output the voltage intensity that meets the requirements of the electron gun, but the volume is generally large. How to design such a high-voltage power supply that can work safely and reliably in such a cramped volume will be a difficult problem.
