Description
Technical field
The present invention relates to the pulse power, particularly relate to a kind of electron gun special type dual-pulse power supply.
Background technology
Electron gun is to accelerate a kind of device that electron bombardment target screen is luminous, and it is launched has certain energy, certain line
And speed and the electron beam of angle.(direction of this electron beam and intensity can control, generally by hot cathode, control electrode and
Some accelerating anodes etc. form) electron gun is used for providing electron beam, and bombard fluorescent screen and form the image of different tonal gradation.Electricity
Sub-rifle is generally divided into heat emission and field emission two kinds；The function of electron gun is to provide the electron beam meeting requirement, and electronics
The material of rifle and process structure must account for again electron gun and be prone to processing with easy to use.
Dual-pulse power supply has another name called flat ripple/two-way pulse wave rearrangeable switch power supply, and it is by being direct current by industrial frequency AC electric rectification
High pressure dual-pulse power supply dual-pulse power supply power supply, produces low-voltage high-current power source by high frequency voltage transformation and high-frequency rectification, then
It is filtered into pure DC source by LC, is then delivered to an asymmetric full-bridge circuit (also known as chopper circuit), produce one
Individual artificial flat ripple (the purest direct current) or bidirectional pulse square wave.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of electron gun special type dual-pulse power supply, it is possible to accurately control to bang
Hit gun cathode metal pulse voltage, and can be shown at the enterprising row number of instrument by dipulse voltage, simple and clear.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of electron gun extraordinary double arteries and veins
Rush power supply, it is characterised in that including: CPU element, man machine interface, pulse driving circuit and pulse load circuit.
High-voltage pulse power source divides high direct voltage to produce；Arrester switch K triggers (including LCR to trigger);Positive and negative high pressure passes through
Silicon stack D, D1 charge to filter capacitor C1, C2, and driven by motor gap rotates, and C1 passes through lead inductance L1, and resistance R1 is to C2
Charging, positive high voltage discharge switch K closes, and electric capacity C2 is to load discharge.Thereafter C4 is charged by C3, and C4 is to load discharge, and this is
One complete cycle, just, high pressure by one voltage-multiplying circuit realize, low pressure input, High voltage output, by electric resistance partial pressure,
Series resistance current limliting.
Preferably, described CPU uses AT89C42 chip, and it carries the EEPROM of 8K, it is not necessary to extend out program storage,
And operating frequency can reach 24KHz, can timing accurately by exterior terminal.
It is different from the situation of prior art, the invention has the beneficial effects as follows: can accurately control to bombard gun cathode gold
Belong to pulse voltage, and can be shown at the enterprising row number of instrument by dipulse voltage, simple and clear.
Accompanying drawing explanation

Charging C2, positive high voltage discharge switch K closes, and electric capacity C2 is to load discharge.Thereafter C3 to C4 charge, C4 to load discharge,
This is a complete cycle.Just, high pressure by one voltage-multiplying circuit realize, low pressure input, High voltage output, divided by resistance
Pressure, series resistance current limliting.
Described CPU uses AT89C42 chip, and it carries the EEPROM of 8K, it is not necessary to extend out program storage, and work frequency
Rate can reach 24KHz, can timing accurately by exterior terminal.
By the way, the electron gun special type dual-pulse power supply of the embodiment of the present invention overcomes Single Pulse Discharge and causes instead
Answer stored charge on device not discharge the hangover voltage of institute's stroke, strengthen the space electric field of follow-up power pulses stroke；Overcome list
Pulse is learned on the job the shortcoming of spark, improves work efficiency.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description and accompanying drawing content are made convert, or are directly or indirectly used in other relevant skills
Art field, is the most in like manner included in the scope of patent protection of the present invention.
