摘要：

高压直流电源的纹波抑制一直是激光器电源技术的关键问题。针对用于大功率激光器的高压直流电源的纹波抑制问题，采用全波倍压整流电路对电源电压纹波进行抑制，并利用神经网络对整流电路中的倍压级数及电容容量进行优化。按照优化的参数在该实际高压电源中进行了纹波抑制实验，结果表明所设计的整流电路对纹波的抑制效果显著增强。

Abstract:

Ripple suppression of high voltage DC power supply is always a key issue in laser power technology. For the ripple suppression problem of high voltage DC power supply for high power lasers, full wave voltage doubler rectifier circuit is used to suppress the ripple of power supply voltage, and the voltage series and capacitor capacity in rectifier circuit are optimized by using neural network. According to the optimized parameters, the ripple suppression experiments are carried out in the actual high voltage power supply. Results show that the designed rectifier circuit can significantly enhance the ripple suppression effect.

Key words: high voltage DC power supply; laser; ripple suppression; rectifier circuit; neural network
