| Abstract: | The welding inverter single-phase bridge circuit and control circuit design based on DSP2812 was introduced.Through the inverter circuit input voltage and output current sampling,the fuzzy-PI control algorithm was used to control the mode to achieve a constant welding current purposes.On this basis,a 3 kW/kHz IF inverter spot welding machine was developed.The experiment results show that the system is stable,reliable,and able to better put into industrial use. |
