摘要
本文在分析试验的基础上，采用复合隔离型逆变电路和非高频起弧割炬，配以相应的内拖外特性控制方式和电路设计法，研制成功了低干扰高可靠性的逆变式空气等离子切割机。实验表明，该机具有可靠性高，切割质量好，操作简便等特点，为空气等离子切割工艺提供了一种新型的优良设备。
On the basis of the analzying and testing, a new kind of air plasma cutting power sourcehas been put forward in the article. With an complex-isolated invertor, this set, which is especialy designedfor Non-HF igniting, has a special output characteristc with a low starting carrnet. Low disturbance andhigh reliability can be said the main properties of the power source. It has been proved by lots experimentsto be a excellent cutting machine with perfect. cutting quality and easy-operating
