摘要
为了提高恒流焊机的稳定性,引入了双电流闭环控制,并阐述了双闭环电流控制的机理。结合电流型芯片UC2856,设计了一台基于双电流闭环控制的400 A/36 V恒流焊接电源,并设计了辅助保护电路。通过电源的设计过程和测试结果分析,该电源具有很好的抗短路能力和输出特性,满足设计要求。
In order to improve the stability of the constant current welding power supply, the dual closed-loop current control and the mechanism of the dual closed-loop current control are introduced.Combining with the current-type chip UC2856,400 A/36 V constant current welding power supply based on dual closed-loop control is designed, and the related protective circuits is designed.Through designing process of power supply and testing results analysis, the power supply has good anti-short-circuit capability and output characteristics, meets the expected design requirements.
