Description

Saturable pulse transformer replaces all solid state Marx generator of gas switch
Technical field
The present invention relates to the Marx generator in high power pulse modulation technique field, especially a kind of all solid state Marx generator that adopts low inductance wire wound Saturable pulse transformer replacement gas switch.
Background technology
The pulse power modulation technique is that the electric field with higher density or the magnetic field energy that a kind of handle " slowly " stores carried out Fast Compression, conversion or the direct electric physical technique that discharges to load, and voltage transformation wherein and switching technique are crucial.In recent years, the pulse power modulation technique obtained good application in High-Power Microwave, high power pulsed laser, surge generator, dielectric barrier discharge, material surface processing, industrial waste gas waste water treatment, food sterilization sterilization and the various fields such as biomedical, and these are used paired pulses power modulators and have proposed the rerun requirement of frequency, solid state and long life of high power, height.In the pulse power modulator, two kinds of pressure build-up techniques commonly used comprise pulse transformer technology and Marx generator technology, the two belongs to respectively inductive energy storage type and capacitor energy storage type technology, each has something to recommend him with regard to technical advantage, be the most important pressure build-up technique of two classes arranged side by side in the high power pulse modulator.
The Marx generator is to realize many pulse capacitors elder generation charged in parallels, discharged in series again, thereby realizes a kind of high voltage pulse output device of output voltage stack.Existing technology report about common Marx generator comprises Patrik Appelgren, the paper that the periodical " plasma science transactions " (IEEE Transactions on Plasma Science) that Mose Akyuz and Mattias Elfsberg etc. sponsored in IEEE-USA (IEEE) in 2006 is delivered " a kind of research of the compact High Power Microwave System based on reflex triode and Marx generator " [Patrik Appelgren, Mose Akyuz and MattiasElfsberg, " Study of a compact HPM system with a reflex triode and a Marx generator; " IEEETransactions on Plasma Science, 2006, Vol.34, No.5, pp.1796-1805], and " high power pulsed source " (Wang Ying that published and distributed in 1991 of writing of Wang Ying, " high power pulsed source ", Beijing: Atomic Energy Press, 1991, the 1.5th joint " inductance isolated form Marx generator " (hereinafter referred background technology one) in the chapter 1 " capacitance energy storage high power pulsed source " in pp.24-28).In such technology report, common Q level (Q is integer, Q 〉=1) inductance isolated form Marx generator is by Q isolation inductance L c, a Q grounded inductor L i, a Q capacitor C 0, a Q gas switch G 1-G Q, main switch G s(gas switch) and load resistance R LForm.Q level Marx generator comprises Q level Marx unit altogether, and every one-level Marx unit comprises 1 isolation inductance L c, 1 grounded inductor L i, 1 capacitor C 0With 1 gas switch.External power source passes through the isolation inductance L of first order Marx unit at first cGive the capacitor C in this unit 0Charging, because capacitor charging time is longer, the isolation inductance L cWith grounded inductor L iInduction reactance less, the charging voltage ripple from first order Marx unit successively bamboo telegraph to the second level ..., Q level Marx unit, and realize the capacitor C in the Marx at different levels unit 0Successively charging, in the charging process, all gas switch all is in off state.After capacitor chargings at different levels are complete, the gas switch G in the first order Marx unit 1By the external forced triggering and conducting, ON time is the ns level, at this moment isolates inductance L cWith grounded inductor L iInduction reactance can be very large, the C in the first order Marx unit 0Begin over the ground end discharge, and all the other Marx electric capacity at different levels are similar to then and do not discharge owing to isolate the buffer action of inductance and grounded inductor.In the first order Marx unit, G 1Quick pressure conducting make originally charging voltage be+U 0C 0High-pressure stage directly links to each other with the ground end, so that C 0High-pressure side current potential moment becomes 0 current potential (earth potential), and C 0Both end voltage+U 0But can not sport 0, C 0The current potential of former earth terminal becomes-U 0, to guarantee C 0Two ends+U 0Electrical potential difference; Gas switch G in the Marx unit, the second level 2High-pressure side and Marx unit, second level C 0High-pressure side connects, gas switch G 2Low-pressure end and first order Marx capacitor C 0Former earth terminal links to each other, therefore when first order Marx capacitor C 0The current potential of former earth terminal becomes-U 0After, G 2Two ends moments will bear+U 0-(U 0The 2U of)=+ 0Overvoltage ,+2U 0Than G 1The limit withstand voltage of design is slightly high ,+2U 0G under the overvoltage effect 2Also fast conducting, same so that C in the Marx unit, the second level 0Current potential moment of former earth terminal becomes-2U 0 According to identical rule, until G QSelf breakdown conducting under overvoltage, C in the Q level Marx unit 0Current potential moment of former earth terminal becomes-QU 0, capacitors at different levels are realized series connection fully in the Q level Marx generator, therebetween, and from G 1Constantly risen by the external trigger conducting, be during this period of time Marx generator settling time until capacitors at different levels are realized connecting fully in the Q level Marx generator; Last Q level Marx general-QU 0Negative high voltage be applied to main switch G sOn, make G sSelf breakdown conducting under overvoltage is at load R LUpper formation negative high-voltage pulse output.
Yet, the common Q level Marx generator of tradition need to adopt Q different gas switch to control, first order gas switch need to adopt the external trigger system to carry out forced-triggered, in the larger situation of discharging current, gas switch exists serious ablation and shake, is difficult to the Marx generator is brought up to 10 useful life 5More than inferior, Marx generator progression is more, and the shake of Q gas switch integral body is larger, and the stability of a system is poorer, and the switch insulation recovery is slower, and system is difficult to realize the high repetition frequency operation; In common Q level Marx generator network, charging port is positioned at an end, and is slower away from the Marx capacitor charging speed at different levels of charging port, causes Q level Marx capacitor charging inhomogeneous, affects the voltage Overlay of discharged in series; Because the Q level gas switch of common Marx generator punctures conducting step by step, therefore Q level Marx capacitor is not to be desirable discharged in series relation, there is certain settling time in the series connection of capacitor discharges at different levels, part in the Marx generator energy that electric capacity at different levels store in settling time will consume on charging resistor, earth resistance and connection resistances, cause energy loss.Therefore, traditional gas switch Marx generator can not satisfy the operation of pulse power modulator high repetition frequency, solid state and the designing requirement of long life preferably.
In view of the defective of common gases switch Marx generator in the background technology one, the researcher adopts the high-power semiconductor switch of solid state, develops all solid state Marx generator.In all solid state Marx generator, the all gas switch is all substituted by high-power semiconductor switch device (such as thyristor, insulated gate bipolar transistor IGBT, mos field effect transistor MOSFET etc.), realizes all solid stateization and the long-life of switch.The technology report of existing all solid state Marx generator based on high-power semiconductor switch comprises Li Hongtao, Wang Chuanwei, the paper that Wang Lingyun etc. delivered at " light laser and the particle beams " in 2012 " all solid state Marx generator of 500kV " (Li Hongtao, Wang Chuanwei, Wang Lingyun, etc., " all solid state Marx generator of 500kV; " light laser and the particle beams, 2012, Vol.24, No.4, pp.917-920) (hereinafter claiming background technology two).The all solid state Repetitive Marx Generator of 500kV mainly is made of charge control system, pulse power system (i.e. main Marx generator part), load system, master control and auxiliary system four parts.Charge control system is comprised of high voltage source, middle energy storehouse and charging control switch, finishes mains supply to the conversion of high voltage direct current.Pulse power system is finished direct current energy to the conversion of high-voltage pulse energy, and it is comprised of IGBT switch module, energy storage and pulse shaping module; IGBT switch module completing circuit switches and the pulse modulation function, and it is made of 8 3300V/1200A IGBT series connection, and design work voltage is that 20kV, operating current are 1kA; The IGBT switch module comprises that also IGBT drive plate, IGBT drive secondary power system, even volt circuit etc.; Energy storage and pulse shaping module are finished energy storage and the waveform binding function of Marx generator, the 18 grade pulse forming networks (PFN) of this module for being made of 20nF capacitor and 0.1 μ H inductance.The all solid state Marx generator of 500kV is connected to form according to the Z-shaped line structure by 28 pulse power modules.Load system is comprised of ohmic load and oil cooling system, is used for consuming the pulse electric energy of pulse power system output; Ohmic load adopts 200 6.25k Ω/150W metal film solid resistances to consist of with the form of 50 parallel connections in every road, 4 tunnel series connection; The oil cooling system adopts the cooling of 25# transformer oil.Master control and auxiliary system comprise turn-key system and the auxiliary system that is comprised of electrical parameters detection system, switching delay triggering system and cooling system.In all solid state Repetitive Marx Generator of 500kV, adopt altogether 28 * 8=224 all gas switch in the common Marx generator of the incompatible replacement of high-power IGBT switches set, all solid stateization of Marx generator and the frequency that reruns of 50Hz have been realized, improve Marx generator useful life, explored a feasible all solid state Marx generator technology path.
But, because at present high-power semiconductor switch technology and technological level restriction both at home and abroad, withstand voltage and the through-current capability of single tube high-power semiconductor switch (such as thyristor, IGBT, MOSFET etc.) can not reach very high level, therefore at tens kV to hundreds of kV level high voltage and the large current domain of tens kA levels, need to adopt multitube semiconductor switch connection in series-parallel technology could satisfy instructions for use.In the background technology two, 224 series-parallel technology of high-power IGBT switch have been adopted, all pressures and current-sharing to each single tube IGBT switch in each switch module require very harsh, and guarantee the strict synchronous operation of each single tube switch, synchronization accuracy need to be controlled at the ns magnitude, and the time of delay difference opened between 28 switch modules requires less than 10ns, and the Synchronization Control difficulty of this system switching is very big; The use of the great high-power semiconductor switch of quantity causes all solid state Marx generator cost very high, is difficult to promote and realize commercialization; The supporting auxiliary system of all solid state Marx generator is numerous, and the operation control difficulty of system is large, safeguards difficulty.
Too much for adopting the semiconductor switch number in the background technology two, with and the structure that causes and the problem of technical sophistication, can adopt the method for semiconductor switch branch road series inductance, reduce pulse high current peak value that semiconductor switch conducting moment bears and the time climbing of pulse current, thereby reach the purpose that reduces semiconductor switch number and Synchronization Control difficulty.Employing is connected with high-power semiconductor switch with the satiable inductor of resetting system, and then all solid state Marx generator correlation technique that replaces gas switch is reported, comprise F.Hegeler, M.W.McGeoch, paper " a kind of withstand voltage GW level solid state pulse power system " [F.Hegeler that the periodical that J.D.Sethian etc. sponsored in IEEE-USA (IEEE) in 2011 " insulator and electric insulation transactions " (IEEE Transactions on Dielectrics andElectrical Insulation) is delivered, M.W.McGeoch, J.D.Sethian, H.D.Sanders, S.C.Glidden and M.C.Myers, " A durable gigawatt classsolid state pulsed power system; " IEEE Transactions on Dielectrics and Electrical Insulation, 2011, Vol.18, No.4, pp:1205-1213.] (hereinafter claiming background technology three).12 level full solid state Marx generators are mainly by 12 100kV/60nF capacitor C 1-C 12, 11 130 μ H the isolation inductance L Ch2-L Ch12, 12 50kV level high voltage silicon stack D 1-D 12, 12 roadlock buffer resistance R Ch1-R Ch12, the integrated thyristor switch module of 12 road 48kV levels Thy 1-Thy 12, 12 tunnel satiable inductor SMA independently 1-SMA 12, No. 12 magnetic core reset circuits, magnetic switch Ms MainForm.12 level full solid state Marx generator basic structures and common inductance isolated form Marx generator architecture are basic identical, just adopted the integrated thyristor switch module series connection of multichannel satiable inductor to replace the multipath gas switch, adopt the multichannel high voltage silicon stack to replace the multichannel grounded inductor, and adopt magnetic switch to replace gas switch as Marx generator main switch.Compare with background technology two, single tube high-power thyristor switch is withstand voltage and through-current capability obviously is better than single tube IGBT switch, adopts integrated thyristor switch module to be conducive to reduce semiconductor switch number and Synchronization Control complexity thereof.Before the work, 12 road satiable inductor SMA 1-SMA 12Magnetic core resetted respectively by No. 12 magnetic core reset circuits, each road reset circuit is comprised of reset resistor and the inductance that resets, and by outer triggering signal control, main switch MS MainMagnetic core also to reset first; During work, the external charging power supply is by 30 Ω charging resistor R Ch0Give 12 grades of Marx generator capacitor C 1-C 12Charging, charging process are isolated inductance L for 11 for up to 72ms Ch2-L Ch12With 12 road high voltage silicon stack D 1-D 12On not impact of charging process, the 12 tunnel are used for the damping resistance R that damping Marx generator loop vibrates Ch1-R Ch12Also consume hardly rechargeable energy; After charging process is complete, the integrated thyristor switch module of front two-stage Thy 1And Thy 2By the external trigger conducting, front two-stage Marx generator capacitor C 1And C 2Discharge makes front two-stage satiable inductor SMA simultaneously 1And SMA 2Rapid saturation conduction, then 10 grades of integrated thyristor switch module Thy 3-Thy 12Automatically finish triggering by Marx generator loop, rear 10 grades of satiable inductor SMA 3-SMA 12Rapid saturation conduction in succession, thus make 12 grades of Marx generators from charged in parallel state shift discharged in series state, and adopt 12 road satiable inductor SMAs less than 20ns the settling time of Marx generator 1-SMA 12With 12 road integrated thyristor switch module Thy 1-Thy 12The purpose of series connection is to reduce the current time climbing of integrated thyristor module, guarantees integrated thyristor module safe and stable operation; 12 grades of Marx generator capacitor C 1-C 12In the series boosting process, as the magnetic switch MS of main switch MianAlso born simultaneously the voltagesecond product corresponding to pulse high-voltage of continuous increase, when this voltagesecond product reaches magnetic switch MS MianBehind the specified voltagesecond product of magnetic core, magnetic switch MS MianSaturation conduction, 12 grades of Marx generator capacitor C 1-C 12Series connection is discharged to external loading, the output HIGH voltage pulse.This 12 level full solid state Marx generator frequency that reruns is 20Hz, and surpass 1.15 * 10 useful life 7Inferior.
Background technology three has successfully been explored a 200kV level full solid state Marx generator technology path, has realized the 20Hz repetitive operation and 10 of all solid state Marx generator 7Inferior useful life.But this technology path does not solve the inconsistent and charging non-uniform phenomenon of the Marx capacitor charging speed at different levels that exist in the common Marx generator; The 12 road integrated thyristor modules that adopt in the system, although greatly reduce the number of semiconductor switch, its cost and cost are still higher; Adopted the use of connecting with 12 road integrated thyristor modules of 12 road satiable inductors in the background technology three, cause system need to adopt 12 of a large amount of magnetic cores (〉), and per 1 road satiable inductor all needs extra auxiliary reset circuit and external control system, has increased complexity and the Synchronization Control difficulty of system.
With respect to the series-parallel high-power semiconductor switch of multitube, the magnetic switch that volume is slightly large is fit to tens kV more to hundreds of kV high voltage and the large electric current application of tens kA.Employing longer magnetic switch of life-span replaces all gas switch in high-power semiconductor switch and the common Marx generator, and then all solid stateization and the long-life of realizing common Marx generator, is a technology path with important development prospect.Adopt magnetic switch to replace the correlation technique report of all solid state Marx generator of gas switch fully, comprise the horse guest, Ding Weidong, the paper that Li Feng etc. delivered at " light laser and the particle beams " in 2010 " based on the repetition rate impulse voltage generator of magnetic switch " (horse guest, Ding Weidong, Li Feng, etc., " based on the repetition rate impulse voltage generator of magnetic switch; " light laser and the particle beams, 2010, Vol.22, No.3, pp.469-473) (hereinafter claiming background technology four).3 level full solid state Marx generators in the background technology four are by capacitor C 3-C 5, coupling inductance L 11-L 32, magnetic switch K 1-K 3With load capacitance C LConsist of, basic identical with the structure of common inductance isolated form Marx generator, the magnetic switch winding that has just adopted multichannel to be total to magnetic core has replaced the gas switch in the common inductance isolated form Marx generator, thereby has realized the solid state of Marx generator.Because isolation inductance L 11And L 12, L 21And L 22, L 31And L 32Be respectively 3 pairs of coupling inductances that intercoupled by 3 independent magnet rings, can under less winding condition, realize larger charging isolation inductance.During work, the external charging power supply is from charging port simultaneously to Marx capacitor C at different levels 3, C 4And C 5Charging, altogether magnetic core magnetic switch K 1, K 2And K 3To bear pulse high-voltage, because the charging interval is longer, the isolation inductance L 11And L 12, L 21And L 22, L 31And L 32Induction reactance very little, can not affect charging process; Work as K 1, K 2And K 3In the corresponding voltagesecond product of any one magnetic switch winding charging voltage of bearing when reaching the specified voltagesecond product of magnetic core, core structure determines no matter whether the voltagesecond product that other several roads magnetic switches bear also reaches the specified voltagesecond product of magnetic core altogether, magnetic core is all with saturated, makes simultaneously 3 road magnetic switch K on the common core 1, K 2And K 3Force simultaneously conducting, make 3 grades of Marx capacitor C 3, C 4And C 5Be the discharged in series state from the charged in parallel state-transition; C 3, C 4And C 5Series connection is to load capacitance C LDischarge is at C LUpper formation high voltage pulse.
Background technology four adopts the method that is total to the magnetic core magnetic switch that all solid state Marx generator based on magnetic switch has been carried out significant desk study, solved the large problem of multistage gas switch shake in the common Marx generator, utilize each road of the saturated pressure of magnetic core altogether the principle of simultaneously conducting of magnetic core magnetic switch shortened Marx generator settling time, and improved common Marx generator useful life and the frequency that reruns, greatly reduce the cost of system.But background technology four proposes the Marx generator architecture still adopts the coil inductance that comprises magnetic core as charging inductance and isolation inductance, can not solve the problem that multistage Marx generator capacitor charging speed at different levels are inconsistent, charging is inhomogeneous; And there is not the magnetic core resetting system in the Marx generator, behind the magnetic switch saturation conduction, work next time and just can not export again the same polarity pulse, therefore this system can only export the bipolar pulse that positive-negative polarity alternately occurs, and there is not the assurance that resets of magnetic core resetting system, the each saturation condition after hours of magnetic core is inconsistent, so the output pulse of system is difficult to stable; Load capacitance C LWith final stage Marx capacitor C 5Between do not have main switch to isolate, will cause Marx generator capacitor charging voltage drops at different levels, and can be at load capacitance C LUpper generation prepulsing; Background technology four adopts the magnetic switch of common wire wound structure, and pulsactor is larger, in Marx capacitor C at different levels 3, C 4And C 5Be 3 ~ 5nF magnitude, and load capacitance C LUnder the prerequisite for the 1nF magnitude, 3 grades of Marx generator output voltage leading-edge pulse times can be less than 80ns, in case Marx capacitor C at different levels 3, C 4And C 5Increase to hundred nF magnitudes, Marx generator output voltage leading-edge pulse time will increase to inferior μ s even μ s level, be unfavorable for that the Marx generator exports hundred ns level fast forward position pulses, therefore the magnetic switch of common wire wound structure determines the series connection progression unsuitable excessive (Q≤5) of all solid state Marx generator; In order to realize 3 grades of solid-state Marx generator output 17kV high voltage targets, the outside primary return of solid-state Marx generator has adopted pulse transformer and 2 grades of magnetic pulse compression networks of a 4:77, just the 320V low-voltage is converted into the 6kV charging voltage on the solid-state Marx generator electric capacity at different levels, elementary charging system is huge and complicated.Therefore, how successfully solving the above-mentioned important technological problems that full magnetic switch replaces all solid state Marx generator existence of gas switch, is the key that determines full magnetic switch type all solid state Marx generator technical scheme feasibility and practicality.
Saturable pulse transformer is that a kind of its magnetic core unsaturation attitude of utilizing is to the conversion of saturated mode, the conversion of realization from the transformer transformation function to magnetic switch saturation conduction function, and then on a kind of device, realize simultaneously the Pulsed power device of transformer and two kinds of independent component functions of magnetic switch, Saturable pulse transformer can make system's magnetic core consumption, weight, volume and cost significantly reduce, and the layout of discrete transformer and discrete magnetic switch has very significantly advantage in the more traditional pulse power modulator system.Common Saturable pulse transformer armature winding and secondary winding are single wire wound winding, can not be applied in all solid state Marx generator, replace gas switch and high-power semiconductor switch.But, if the structure and mechanism to common wire wound Saturable pulse transformer carries out improvement and bring new ideas, guaranteeing that Saturable pulse transformer possesses higher 25 times of the multiples (〉 of boosting) greatly reduce its pulsactor under the condition, then Saturable pulse transformer will possess and replace gas switch in the common Marx generator and the parts that boost of the elementary charging system in outside are integrated in the Marx generator, improve admissible Marx generator series connection progression Q, successfully solve the huge advantage of numerous inherent technology problems in the existing all solid state Marx generator of full magnetic switch type.
At present, also be in the desk study stage about the technology of all solid state Marx generator of full magnetic switch type, its inherent technology problem is not solved all the time preferably; Adopt the Saturable pulse transformer secondary winding of innovation structure to replace the correlative study that has gas switch, semiconductor switch or common magnetic switch in the Marx generator now, also have no report.The present invention is directed in the background technology four that all solid state Marx generator of magnetic core magnetic switch type capacitor chargings at different levels are asynchronous altogether, magnetic core lacks resetting system and causes the Marx generator only can export bipolar pulse, elementary charge power supply output voltage amplitude is required high (〉 7.5kV), the problems such as the magnetic switch pulsactor is large, adopt a kind of Saturable pulse transformer of multichannel wire wound winding grouping parallel-connection structure, and utilize this Saturable pulse transformer multi-channel parallel and be total to the secondary winding of magnetic core as the magnetic switch of Q level Marx generator, the input of realization low-voltage (＜1kV), low pulsactor, small compact, full automatic control, magnetic core automatically resets, charging is synchronous low-cost all solid state Marx generator evenly.
