A New Automated Trigger Circuit for a Pulsed Nd: YAG Laser
2010Co-Authors: Fatah Almabouada, Djelloul Louhibi, Abderrahmane Haddouche, Abdelkader Noukaz, Ramdan BeggarAbstract:The power supply of flash lamp-pumped a Nd: YAG solid-state laser basically consists of a Trigger Circuit which initiate the ionization of the gas into the lamp, a simmer Circuit that keeps the ionized gas with a low-level dc current and a main discharge Circuit where a storage capacitor is discharged into a flash lamp to pump the Nd:YAG laser. The impedance of the flash lamp presents a nonlinear variation and the gas deionization which can occur between two pulses laser, leading to another manual Triggering operation. To overcome this operation, we give in this paper a new automated Trigger Circuit activated by a delivered signal from the simmer Circuit. This Circuit is simple for implementation and need just few components. It has been simulated by PSpice software and validated by experimental results.

Comparative study of pulse Trigger and DC Trigger Circuit for xenon flash lamp drivers
IEEE Transactions on Dielectrics and Electrical Insulation, 2019Co-Authors: Seung-ho Song, Chan-gi Cho, Su-mi Park, Hyun-il Park, Hong-je RyooAbstract:This paper presents an investigation of Trigger Circuits for xenon flash lamp drivers from the viewpoint of breakdown voltage, high-voltage isolation, and reliability. A comparative study of pulse Trigger and DC Trigger Circuits is provided, focusing particularly on the Circuit structure of each driver for high voltage isolation. Two kinds of Trigger Circuits for xenon flash lamp drivers are developed with a 2.5 kW (500 V/5 A) simmer Circuit for maintaining the xenon lamp ionization. The structure of each Trigger Circuit is the series Trigger type to obtain the advantages of the isolation structure. The outputs of the pulse and DC Trigger Circuits are measured as 21 kV 1.8 μs half-sine wave pulse and above 10 kV DC, respectively. The tests of xenon lamp ignition and the results of the comparison are discussed. The results prove that the both developed Trigger Circuits can be effectively used as xenon flash lamp drivers.

Design and Implementation of Novel Series Trigger Circuit for Xenon Flash Lamp Driver
IEEE Transactions on Plasma Science, 2018Co-Authors: Seung-ho Song, Chan-gi Cho, Su-mi Park, Hyun-il Park, Hong-je RyooAbstract:This paper describes the design and implementation of novel Trigger Circuit (23 kV, $1.7~\mu \text{s}$ , and 0.66 J/pulse) for xenon flash lamp driver. The design is based on a modified flyback Circuit in the discontinuous conduction mode to take advantage of both generating the high voltage from the resonance with output capacitor and connecting the series with main pulse Circuit using the flyback transformer which can carry the full current of several kiloampere at high-voltage side. This design eliminates the requirement for additional high-voltage protection devices in a xenon flash lamp driver. In addition, the unique high-voltage flyback transformer is designed with high turn ratio and low leakage inductance. The detailed design procedure for the resonant Circuit at the output side of the flyback Circuit with the permissible range of the parasitic component of the transformer is described on the basis of simplified analysis of resonant Circuit. To verify the proposed design, computer simulation based on PSpice software and experiments for the proposed Triggering Circuit with a main pulse Circuit was performed. For the experiment, the Trigger Circuit is developed with the specification of maximum 23-kV, 0.66-J/pulse output and tested with a xenon flash lamp (Heraeus P4101) driver consisting of a 1.5-kV, 36-kJ/s main pulse Circuit and a 2.5-kW (500 V, 5 A) simmer Circuit. The experiment is performed in both Triggering without the simmer mode and combining the simmer mode. From the simulation and experimental results, it is verified that the Triggering Circuit can be used effectively, as it exhibits reliable ignition.
