摘要
阐述了脉冲电化学光整加工原理。采用脉宽调制 (PWM )技术发生脉冲信号 ,设计了控制电路和IGBT驱动保护电路 ,研制了专用脉冲电源。应用此电源进行工艺实验 ,证明了实验数据和理论分析的一致性。
The principle of pulse electrochemical finish machining (PECFM) is discussed. The special pulse power supply is researched and manufactured. The PWM is adopted to produce pulse signal. The control circuit and IGBT driving circuit is designed. The performance of the power supply is verified by experiment.
