The igniter of high-voltage gas discharging light in lighting power supply system.
Background technique
For Laser Power Devices, final effective object is gas pumping lamp, discharges through gas pumping lamp and mentions for laser
For pump energy.The ignition operation state of gas pumping lamp is divided into 1- build-up of luminance, three stage of 2- pre-burning and the arc discharge of 3- high pressure, is
A kind of unstable state process gas discharge that each stage is more complicated.
In classical ignition system, as shown in Fig. 1 a, b, figure a circuit belongs to external trigger type, and it is unreliable to light, and is unable to water flowing
Cooling discharge lamp, is not suitable for anticyclonic discharge lamp, schemes the electrode both ends that ignition power in b circuit is crimped onto lamp 9.Therefore master is put
Must add high pressure disconnecting relay 8 between circuit and lamp, often contain in this circuit and give combustion power supply 6.By series resonance original
Reason may know that, the pulse voltage that amplitude is U will be obtained on inductance 4 and capacitor 2, after the boosting of transformer 5, as long as nU value is greater than
The gas breakdown voltage U of lampj, the internal gas of lamp is just breakdown, forms ionization channels, and neutral gas-discharge lamp becomes leading
Body, due to the energy very little of ignition voltage, because the both end voltage of lamp does not fall below the voltage U that main electric circuit provides0, breakdown
After main electricity cannot be ignited immediately, must there is one to give combustion voltage source 6 thus, the output voltage of the power supply is known as ignition voltage.
The effect of the voltage be after the gas of discharge lamp is breakdown, make lamp obtain discharge current increase, the voltage at lamp both ends further under
It will drop, when the voltage at lamp both ends drops below main supply voltage U0When, U0Electric discharge is participated in, makes lamp successively-ignited, is formed stable
Arc discharge.Therefore enough power must be provided voltage of both ends of lamp is made to drop to main supply voltage U by giving combustion voltage source0Value with
Under.To anticyclonic discharge lamp U0Less than 70v, electric current is lighted greater than 10 peaces, therefore gives combustion power supply 6 to provide in a short time
Greater than 700w power.
In above-mentioned ignition system, have the following problems, due to there is the presence of gap 3 in 1 Fig. 1 b, to different lamps,
The gap of gap is adjusted at any time.The electromagnetic interference generated when spark-gap discharge is very big, generates in igniting and smells oxygen, 2 transformations
Device magnetic core is easily saturated, and is not easy to light to hyperbar lamp (such as krypton lamp), and 3 must have one can provide the auxiliary of enough energy in the short time
Power supply is helped, for these reasons, we have invented one kind can overcome the New Type of Ignition System of the classical ignition system above problem,
Circuit is simply at low cost, and igniting is reliable.
Summary of the invention

Tap is connected to one end of resonant capacitance, the other end ground connection of resonant capacitance at two circles of input terminal；Step-up auto-transformer
Output end be connected with the anode of discharge lamp, the minus earth of discharge lamp；
Two groups of output voltages of the inversion piezoelectric transformer are charged to centainly to output capacitance and high-voltage energy storage capacitor respectively
Voltage.It is E that voltage is obtained in output capacitance0, it is U that voltage is obtained in high-voltage capacitance0；
After the thyristor that discharges is opened by driving signal, the voltage on high voltage energy-storage capacitor passes through boosting self coupling transformation
The primary coil 1 of device, 2 ends are charged to resonant capacitance, and charging current generates high-voltage pulse in the high-voltage end of step-up transformer, should
High-voltage pulse punctures lamp；Due to being charged to the resonant capacitance, as the voltage for giving right power supply, γ is boosting self coupling transformation
Device boosting coefficient, γ > > 1；Resonant capacitance is after lamp is breakdown, which further discharges to lamp, under continuing voltage of both ends of lamp
Drop, until lower than the discharge voltage E in output capacitance0, at this moment output capacitance is discharged to lamp, completes lighting for high-pressure discharge lamp
Process.
The igniter of capacitor resonance punching of the present invention is substantially exactly the resonant charging process using resonant capacitance
Combustion voltage is given in formation.Gas-discharge lamp is lighted in the unification of both high-voltage pulses formed in resonant charging process simultaneously.
