杜贵平 向锷 张薇琳 . 全数字控制大功率高频微弧氧化电源[J]. 华南理工大学学报(自然科学版), 2011 , 39(3) : 58 -61 . DOI: 10.3969/j.issn.1000-565X.2011.03.012
Proposed in this paper is a high-frequency power supply with fully digital control for micro-arc oxidation.The authors introduce the structure and working principle of the system,and describe the design of two-stage full-bridge inverter with PWM for multi-characteristic output in detail.With the adoption of fully-digital DSP control,the system can output multi-characteristic waveforms as desired.Experiment and operation results show that the proposed power supply fully meets the requirements of micro-arc oxidation and is capable of outputting waveforms with variable frequency and amplitude.
