Development Of YAG Pulse Laser Power Supply System Based On DSP2407

Depth analysis of this article YAG pulsed laser power working principle, in accordance with xenon lamp special electrical characteristics of the design of hardware circuits and software programs. MOSFETS using half-bridge MOSFET inverter to SG3525-driven power PWM technology designed to TLC5620 to change the DAC output voltage, the DSP2407 system power control, a detailed analysis of the main parameters of the road and power systems specific circuit design. Through detailed experiments show that the small pulse laser power does not have the traditional power of the excellent performance. Power to achieve the technical indicators: the frequency of 0～20Hz continuously adjustable output voltage 800V～1200V continuously adjustable, xenon lamp trigger voltage 4000V～6000V. For xenon lamp-pumped YAG laser on the driver's request, developed YAG pulsed laser power. And to improve the switching frequency, greatly reduces the volume and weight of power. Power in the actual operation, stable and reliable. Through theoretical analysis and circuit practice, completed a new high-performance small-scale power supply of pulsed laser system hardware circuit.
