Continuous laser power supply


  A continuous laser power supply is a high-performance, self-igniting, constant current power supply

  The power supply uses a constant frequency, variable width method to achieve high-precision constant current output. The output current ripple is small, and the stability is high. The ignition part uses a series high-voltage package to strike an arc, LC secondary high-voltage relay, and a three-stage current continuation method of low-voltage constant current continuation arc current. Coupled with an ignition monitoring circuit, it achieves automatic ignition, with a first-time ignition success rate of over 99%. The high-voltage pulse waveform rises slowly, and the intensity can be adjusted in stages to adapt to the dispersion of the breakdown voltage of different krypton lamps, and it can also reduce the sputtering of electrode materials and reduce the adverse effects of high-voltage triggering on the service life of the krypton lamp.
