摘　　要：为满足高功率脉冲半导体泵浦激光器相干合成的特殊需要,设计6路同步输出的电源阵列,实现了工作电压0~400 V自适应调整、工作电流0~1 200 A、脉冲宽度200μs^1 000μs、重复频率1 Hz^20 Hz均可任意调整的高电压、大电流脉冲输出。在保证技术指标实现的同时,着重解决阵列电源的同步输出、电压自适应和可靠性保护等问题。试验结果表明,该阵列电源的同步一致性可达到99%,输出电流精度达到0.1 A,已在"六路激光相干合成"研究中得到应用。To meet special needs of the high power pulsed diode-pumped laser coherent synthesis, this paper designs six simultaneous output power arrays to achieve the high-voltage and high-current pulse output with adaptive working voltage 0-400 V, current 0-1 200 A, pulse width 200μs- 1 000 μs and repetition frequency 1 Hz-20 Hz, which can be adjusted. It ensures technical indicators, and focuses on solving the array power synchronous output voltage and reliability of adaptive protection and other issues at the same time. The results showed that, the array power synchronization consistency can achieve 99% and output current accuracy is of 0.1 A. It has been applied in the ＂six-way laser coherent synthesis＂ study.
