A Digital High-power Micro-arc Oxidation Power Supply with Multi-degree of Freedom

分析了传统的氧化电源在镁合金、铝合金表面处理应用中存在的主要问题,提出了一种应用于镁合金、铝合金微弧氧化的数字化多自由度大功率的双极性不对称脉冲电源。介绍了其工作原理、控制方法、主要结构、试验结果以及现场应用情况。

First, we discuss the main problems of traditional oxidation power supplies in applications of magnesium alloy and aluminum alloy surface treatment. And then, we propose a digital micro-arc oxidation bipolar asymmetric pulse power with multi-degree of freedom for the applications mentioned above. Also, the operation principles, control methods, central structure, test results and field application are illustrated in this paper.
