Description
Technical field
The present invention relates to plasma discharging teclmiques field, a kind of DBD high frequencies based on magnetic pulse compression of specific design are double
Polarity millimicrosecond pulse generator.
Background technology
In recent years, atmospheric pressure nonequilibrium plasma is received more and more attention because of its unique advantage.Due to it be
The low temperature plasma discharged in the air of surrounding causes the application for being relatively difficult to realize originally to come true, such as biological
Medical science；Simultaneously as atmospheric non-equilibrium plasma eliminates expensive and extremely cumbersome vacuum system so that its cost
Substantially reduce, one of them very important application is exactly material surface modifying.
DBD (dielectric barrier discharge) plasmas can produce large area under atmospheric pressure because of it
Uniform glow discharge either Townsend avalanche and great industrial application value.Its final application effect and plasma characteristics are close
Correlation, and plasma characteristics are mainly determined by its excitation power supply.Generally, the power supply for producing DBD plasmas is mainly adopted
Encouraged with ac high-voltage, but want to obtain Uniform Discharge, to dielectric material, supply frequency, gap structure have it is very high will
Ask.With the development of Pulse Power Techniques, research is found when driving the traditional exchange driving of replacement using ns pulse voltages, soon
The voltage that speed rises can ionized gas rapidly, streamer development time is short, effectively inhibits and discharges to spark or arc mode
Change, therefore it allows one to obtain uniform nonequilibrium plasma in bigger parameter area.
In order in several millimeters of gap obtain DBD plasmas, it is necessary to pulse voltage amplitude be tens of kilovolts, frequency
Rate is hundreds of hertz to few kilohertz.Generally, obtain the high repetitive frequency pulsed voltage of high voltage mode be using solid-state switch as
The voltage increase technology of core, typical solid-state switch includes semiconductor switch and magnetic switch.Based on semiconductor switch
Typical topology is Marx generators, and its efficiency high, response is fast, frequency, pulsewidth and amplitude interior stepless adjustable in a big way,
But semiconductor switch is pressure-resistant relatively low, when requiring compared with high pulse voltage, required Marx generator series increases, number of switches
It is multiplied, causes corresponding triggering and isolation technology to complicate, system reliability is substantially reduced.And magnetic switch is relative to half
Conductor switchs its pressure-resistant and through-current capability and greatly increased, and does not produce abrasion substantially or deteriorate, therefore, it is possible to greatly simplify
Circuit.But, for magnetic switch, once next task just can be carried out after magnetic-reset, so as to also cause magnetic switch
It is highly suitable for the Pulsed power generator of high repetition frequency.
Because pulse power parameters can directly affect DBD plasma discharge characteristics, including repetition rate, polarity of voltage,
Rising edge etc., wants to explore its changing rule, possesses the adjustable pulse power of a set of multi-parameter essential.And above-mentioned magnetic compression
System has the following disadvantages applied to DBD plasma discharges：1. frequency is not generally high.The reset for being limited to magnetic switch is either low
Controlling switch is pressed, the working frequency of these usual magnetic compression systems is not high, substantially all in below 1-2kHz, but currently for height
The research system not enough of the lower DBD electric discharges of frequency.2. the magnetic compression system of the studies above is generally operational in the case of unipolarity, and is ground
Study carefully and show, DBD discharge processes have obvious difference with unipolarity under Bi-Directional Pulsed Voltage Technique.Think in text, due to DBD electric discharges
The accumulation of middle dielectric material surface charge, can produce an electric field opposite with applied pulse polarity, weaken next pulse
Produced electric field；And when using bipolar pulse, because the electric field of pulses generation and the electric charge electric field of accumulation are in the same direction, Neng Gouyou
Effect reduction firing potential.
