数控YAG激光加工系统电源的研究及改进

Research and improvement on power supply of digital controlled YAG laser processing system

针对串联谐振式激光电源存在充电能力不足的问题,对其产生原因进行分析,讨论了串联谐振式逆变电源的运行方式对平均输出功率的影响,并提出改进的串并联谐振式设计方案,用于千瓦级大功率的YAG激光加工系统,通过实验进行了验证.

Due to the insufficiency of the charging capacity of seriesresonant, the production process is analysed. The effect of the operation mode on the average output power is discussed. The supply of YAG laser processing system with big power almost works in state of open circuit. An improved seriesparallellconnection circuit project is proposed, the conclusion is testified by experiments.
