| Abstract: | A control system of IGBT inverter welding machine based on TMS320F240 was designed. DSP minimum system, serial communication interface,serial peripheral interface circuits were introduced. According to the output PWM waveform from DSP, a special circuit was devised for dividing one PWM pulse into two. The DSP development environment,usage of CCS,and the way to develop DSP software were illuminated. And the characteristics of COFF files, command files and head files were analyzed.The function of system software was also analyzed.A digital control program for inverter welding machine was realized by using modularized software design method. Experimental results indicated that the circuit is reliable and the control is easy,showing the superiority of digital welding machine. |
