AI Technical Summary

Problems solved by technology

The electromagnetic interference generated during spark gap discharge is extremely large, and oxygen smell is generated during ignition. 2. The magnetic core of the transformer is easily saturated, and it is not easy to ignite high-pressure lamps (such as krypton lamps). 3. There must be an auxiliary that can provide enough energy in a short time Power supply 6. Based on the above reasons, we have invented a new type of ignition device that can overcome the above problems of the traditional ignition system. The circuit is simple and low cost, and the ignition is reliable

Description

technical field [0001] The invention designs an ignition device of a capacitor resonance charging type high-pressure gas discharge lamp, which belongs to the ignition device of a high-pressure gas discharge lamp in a laser power supply and an illumination power supply system. Background technique [0002] For the laser power supply, the final object of action is the gas pump lamp, which provides pumping energy for the laser through the discharge of the gas pump lamp. The ignition working state of the gas pump lamp is divided into three stages: 1-glow, 2-pre-combustion and 3-high voltage arc discharge, which is a relatively complicated unsteady gas discharge process in each stage. [0003] In traditional ignition systems, such as Figure 1a , b, figure 2 As shown, the circuit in Figure a is an external trigger type, which is unreliable to ignite and cannot be cooled by water. It is not suitable for high-pressure discharge lamps. The ignition voltage in the circuit in Figure...
