提高微等离子体氧化脉冲电源控制系统可靠性的若干措施

微等离子体氧化技术是一种具有诸多优点的新型表面处理工艺 ,需要可输出双向不对称脉冲的高压脉冲电源 ,而且电源的脉冲幅度、频率、占空比均要在一定范围内连续可调 ,为此设计了以单片机为核心的智能控制系统来实现这一要求。为保证控制系统在电源中可靠工作 ,从软件和硬件两个方面采取了一些抗干扰措施 ,来提高控制系统的可靠性。

Some Measures For the Improvement of the Reliability in the Control System of Micro-plasm Oxidation Impulse Power Source

The technigue of meicro plasm oxidation is a new type surface managing technics with a good many excellences.High volage impulse power source with the ability of outputting the dissymmetry impulse is reguired for this technic.And continuous adjustment to a certainty scope is demanded in the impulse range,freguence and duty ratio of the power source.So the intelligent control system with the core of single chip is designed in this paper,all the above functions can be realised by this system.In addition some anti jamming measures are adopted from two aspects of software and hardware to make the control system in the power source work vell,and the reliability is also improved.
