| 摘 要： | 采用基于ARM7TDMI-S内核的LPC2131微控制器设计了一种全数字化控制的CO2电弧焊逆变电源,完成了硬件电路和软件程序.在设计方案中采用了独立的送丝系统和全桥逆变主电路,选择了送丝速度作为其它焊接参数控制的基准.充分利用了片内软硬件资源,ARM控制器产生一路双边沿PWM脉冲并转换输出,通过电流、电压检测以分时进行短路电流和燃弧电压控制.其硬件结构简单可靠,控制软件可通过升级接口更新算法.文中介绍了设计思路和方法,对全数字化焊接电源研究和开发具有参考价值.

| Abstract: | A full digital inverted power supply based on LPC2131 ARM controller for CO2 arc welding was developed, and the control strategy of short circuiting transfer was proposed.In this system, arc voltage is preset in accordance with the speed of a separate wire feeder, while output current during short circuiting period can be adjusted independently.The digital pulse width modulation signals are generated directly at low hardware expense, and control strategy is implemented through software algorithm.The simplified configuration shows high reliability, and control program can also be updated via upgrade interface for property enhancement. |
