| 摘 要： | 为解决双丝脉冲MIG焊两路脉冲同步、交替和随机三种相位输出的协同控制问题,采用32位的STM32F103ZET6建立基于STM32的一体化双丝脉冲MIG焊电源系统.利用单一STM32芯片实现双丝脉冲MIG焊同步、交替和随机三种脉冲相位输出形式,用STM32内部集成的脉宽调制(pulse width modulation,PWM)模块生成移相全桥软开关PWM信号,以软件方式实现主从机两台逆变电源PWM信号的直接数字化控制,从而实现主从机的高频逆变和低频脉冲波形调制.结果表明,所设计的基于STM32的一体化双丝脉冲MIG焊电源系统满足设计要求,焊接过程稳定、焊接速度快、飞溅小、焊缝成形良好,能实现良好的双丝脉冲MIG焊工艺.

| Abstract: | To solve the quest of realizing synchronization, alternation and random phase control between the master and slave output in the twin-wire pulsed MIG welding, the 32-bit STM32F103ZET6 is adopted in the STM32 based power supply system for integrative twin-wire pulsed MIG welding. Synchronization, alternation and random phase control between two output is realized by single STM32F103ZET6 chip, whose integrated pulse width modulation (PWM) module produces PWM signal for phase-shift full-bridge soft-switching control, so that PWM control for the master and slave inverter is fully obtained by software, with high frequency invert and low frequency wave-form modulation achieved. The results show that the proposed power supply system meets the requirement of the design, as stable and high-speed welding process with little splash is acquired and the weld seam formation is decent. |
