| Abstract: | CO 2 inverter welding system with waveform control is established,in which the TMS320C240DSP is adopted as the central controller.The output characteristic is controlled using a collateral double close-loop method,which is fulfilled by software.The principle of this controlling method and the output waveform are given.The results show that besides its simple structure and easy operation,the system has good controlling performance. |
| Keywords: | DSP waveform control collateral double close-loop |
