Abstract In fuze laser set system , according to the demand of adjustable pulse frequency and adjustable pulse power for the pulse semiconductor laser power supply , a high2power semiconductor laser power supply was designed. A MCU was used as the control chip , a transistor and a MOSFET were used to form the narrow pulse
driving circuit , and a DC2DC converter was designed for the driving circuit. The semiconductor laser power supply features continuous adjustable laser pulse frequency and continuous adjustable laser driving current of 6～ 30A. The power supply was applied in a fuze laser set system. The simulation and experiment results indicate that the laser power supply works normally and performances stably. |
