Description
Technical field
The present invention relates to a kind of xenon flash lamp pump laser power supply, particularly a kind of xenon flash lamp
The charging method of power supply storage capacitor and charging circuit.
Background technology
Usually, high-power pulse solid laser device is more using xenon flash lamps as pumping source,
Pulsed laser energy is converted into light by the electric energy being stored in Large Copacity storage capacitor by xenon lamp
Can again with suitable laser crystal resonator cavity obtain.Therefore in storage capacitors, amount is straight
Connecing the power affecting final pulse laser, the energy of xenon flash lamp laser power supply is changed by following
Subsystem forms:
1, AC-to-DC voltage conversion: this unit alternating voltage is converted to arc light operating institute
The DC voltage needed.
2, storage capacitor: energy-storage capacitor is charged by AC-to-DC voltage conversion circuit,
Electric energy energy is stored and then in every subpulse, stored energy is converted into pump energy.
3, switch or trigger circuit: energy passes through quasiconductor or mechanical switch from energy-storage capacitor group
In controlled being transferred out.
The AC-to-DC voltage conversion of traditional xenon lamp laser power supply is general with storage capacitor charging
There is a following method:
A, directly charge.The method as it is shown in figure 1, three-phase electricity is by after rectifier bridge 1 rectification,
Charge at a slow speed, when storage capacitor voltage and rectified voltage phase to storage capacitor 4 by resistance 2
When difference is less than school, switch 3 Guan Bi, storage capacitor is carried out quick charge.
Said method is simple, and components and parts are few, but the method power factor is low, disturbs electrical network
Greatly, when power is bigger, easily tripping operation or blown out, and boosting can not be carried out cannot
The while of meeting the requirement of high power xenon lamp driving voltage, charging voltage can be with the change of line voltage
And change and cause pulsed laser energy unstable.
B, Industrial Frequency Transformer charge: as shown in Figure 3, three-phase electricity first passes through power frequency and becomes the method
Depressor 5 carries out transformation and is then passed through rectifier bridge 1 rectification, gives storage capacitor 4 slow by resistance 2
Speed charging, when storage capacitor 4 voltage differs less with rectified voltage, switch 3 Guan Bi,
To storage capacitor 4 quick charge.
The simple components and parts of said method are few, but the method power factor is low, big to electrical network interference,
Easily tripping operation or blown out.When current overload, magnetic core of transformer may be saturated, transformer wire
Circle induction reactance strongly reduces electric current and transformator is increased dramatically easily burns.Increase on the basis of method 1
After adding transformator, can boost, but transformer voltage ratio is a fixed value, charged electrical
Pressure can change along with the change of line voltage affects the stability of final laser energy.
C, non-isolated boost charge method (BOOST): during as it is shown on figure 3, just start shooting, Guan Bi is opened
Close the first switch 6, by resistance 2 (metering function), storage capacitor 4 carried out charging battery,
When the voltage phase difference after voltage and three phase rectifier in storage capacitor 4 is less, disconnect the first switch
6, close second switch 7, feedback control circuit 9 exports pulse-modulated signal, by driving
Device 8 controls the break-make of switching tube 11, carries out non-isolated boost charge.
Above-mentioned charging method has boost function, and charging current peak value is automatically by three phase sine alternating current
Pressure limits thus improves power factor.If working in the energy storage inductor 10 continuous CCM of electric current
Pattern, energy storage inductor 10 capacity will be greatly increased, cause inductance itself loss increasing, volume,
The proportional increase of weight, diameter of wire；Continuous current mode pattern can make feedback control loop simultaneously
The design on road becomes extremely complex and is easily produced from Induced Oscillation；Fly-wheel diode 12 exists seriously
Reverse-recovery problems, increase the load of IGBT driver 8 and fly-wheel diode 12 also
Produce strong electromagnetic, can use super for conventional power-factor correction device PFC
Fast recovery diode or silicon carbide diode reduce and even eliminate this problem, but xenon flash lamp
Electric current is connected to pulse discharge circuit due to follow-up, and this portion of electrical current peak value can reach hundreds of several
Kiloampere, prior art cannot meet the requirement of high electric current and reverse recovery time simultaneously.If
Work in energy storage inductor discontinuous current DCM pattern, store inductance 10, switching tube 11 and continue
Stream diode 12 in have the biggest current peak, storage capacitors 4 is entered by this current peak
Bigger voltage ripple can be formed during row charging.Voltage ripple can affect after the electricity of discharge portion
Stream degree of stability, reduction reliability；Ripple current also can cause storage capacitor heating to shorten and use the longevity
Life and the diminishing problem of capacitance.The type selecting of switching tube 11 also can be relatively difficult, in order to
The demand meeting current capacity may use multiple paralleled power switches to use needs to meet device by needs
The transient state current-sharing requirement of part, cannot owing to there is negative temperature effect for some IGBT driver
The mode enabling multitube parallel expands current capacity.
