Abstract :
This paper gives a method of establishing small-signal model for full-bridge inverter arc welding power supply via state-space averaging treatment and linearization method. On the basis of the model, the frequency response reflecting dynamical characteristics of arc welding power supply is analyzed by means of MATLAB. The simulation result has agreement with experiment result as regards dynamical property. The small signal frequent mathematical model established in the paper can reflect basic characteristic of practical arc welding power system.
