It is as follows that the present embodiment is based on its working principle of module superimposed pulse corona discharge plasma power supply：
(1) 380V network voltage boosts by step-up transformer；Then, by PWM full-bridge controllers that AC energy is whole
Flow into any controllable DC voltage of amplitude.Later, DC voltage is reverse into high frequency square wave alternating voltage by single-phase full bridge.Side
Alternating current wave pressure passes through high frequency transformer Ti and fast recovery rectifier pipe, becomes the DC power supply of amplitude stability again.DC power supply warp
Cross buffer Lt1After isolation, for giving discharge capacity device Ck1Power supply；
(2) discharge capacity device Ck1By IGBT switch S1Electric discharge, with loop inductance LstrResonant tank is constituted, meanwhile, Ck1Two
End voltage is quickly transferred to sharpening capacitor device CpOn.With CpHold the rapid increase of voltage, magnetic switch Lm1Saturation rapidly, inductance

Conducting, quadergy pass through RPRelease.
The invention proposes the topological structures for the impulse valtage generator circuit being superimposed based on module.Traditional plasma electricity
Source is boosted by pulse transformer.Since pulse transformer no-load voltage ratio is very big, leakage inductance is very big, causes first order resonance
The harmonic period in circuit is very long (about tens us)；In order to obtain the voltage pulse of rise time about 100ns in load, this is with regard to past
It is past to need 2-3 grades of magnetic switches compressions；But the loss of voltage of every grade of magnetic switch is about 10%, that is to say, that voltage conversion ratio exists

Pressure only needs 1 grade of magnetic switch compression, and not only voltage conversion efficiency is higher, but also the output voltage rise time is faster, is conducive to react
Free electron in device accelerates.The kinetic energy that free electron obtains is bigger, and the oxyradical generated in reactor is more, You Haiqi
The removal effect of body is better.
Present invention employs Cp sharpening capacitor device technologies.For the impulse voltage generator of 100kV or more, module it
Between series conductor wire inductance it is very big (about tens uH).If directlying adopt magnetic switch compression, then pulse rises without sharpening capacitor
Time can not be able to satisfy 100ns rising edge technical requirements very greatly (us grades of approximate number).If sharpening capacitor device is added, the first order is humorous
The harmonic period to shake in circuit can be less than 1us, switch, be applied on magnetic switch Lm1 in this way equivalent to increase level-one magnetic compression
Voltage Flux consumption reduce at double, be conducive to accelerate load Load on rise time.
Present invention employs high-frequency electromagnetic switch Lm1, Lm2 technologies.The working frequency of traditional plasma power supply is only
400Hz mostly uses the nanocrystalline magnet of high squareness ratio as magnetic switch.Based in module superimposing technique scheme, pulse repeats frequency
Rate is promoted to 2000Hz or more.In order to reduce the calorific value of magnetic switch, present invention employs the magnetic compression of MnZn developing magnet to open
It closes.
