文档介绍：摘要
做为现代制造技术的一个重要组成部分和发展方向,精密、超精密加工技术已成为衡量一个的重要标志,而ELID 技术(在线电解修整技术)被世界著名权威机构 CIRP 评价为 21世纪超精密镜面磨削技术的典型代表。
ELID 磨削由磨床、砂轮、电源、阴极、电解液组成,经大量试验研究认为,直流脉冲电源最适宜于 ELID 技术,为此我们研制了直流脉冲电源。该电源由可调压、稳压的电压源和脉冲调制电压源组成。在调压稳压电压源设计中采用二阶工程设计法设计了电压和电流调节器,组成电压、电流双闭环稳压电源,采用集成移相晶闸管模块做为电能变换器件,详细计算了整流主电路主要器件的参数;在脉宽调制部分,采用专用集成电路实现了调频调压,以 IGBT 做为功率变换器件,实现了输出电压的调频调压,并计算了有关参数。

Abstract
Does for a modern manufacture technology important constituent and the development direction, is precise, the ultra precise processing technology has e weighs a country science and technology level of development the important symbol, but the ELID technology (on-line electrolysis repairs and maintains technology) by the world famous anization CIRP appraisal is the typical representative which the 21st century ultra precision mirror surfaces rubs truncates the technology.
ELID rubs truncates by the grinder, the grinding wheel, the power source, the negative pole, the electrolyte posed, believed after the massive experimental study, the direct current pulse power source most is suitable to the ELID technology, has developed the direct current pulse power source for this us. position voltage, the electric current double closed loop voltage-stabilized source, used the integrated phase shifting crystal thyratron module to do for the electrical energy ponent, in detail has calculated the rectification main circuit ponent parameter; In the pulse-duration modulation part, used the special-purpose integrated circuit to realize the frequency modulation to adjust the pressure, did take IGBT as the power ponent, realized the output voltage frequency modulation to adjust the pressure, and has calculated the related parameter.
Key word: Direct current pulse power source; IGBT; Frequency conversion power source; Pulse width
