| Abstract: | The paper introduces the dynamic characteristic and the structure of arc welding power,and gives a method of designing arc welding power which using DSP chip as a controller.The main circuit of bridge invert arc welding power is presented,which applies the state space averaging approach in modeling the system,and develops the small signal model by linearizing the state equation.Transfer functions is derived from the math model of the system as well as dynamic char-acteristics is studied with MATLAB,and the simulation result is consistent with experiment.Conclusion is given,which is useful for analyzing and designing switching power supply. |
