A novel squarewave current inverter suitable for arc welding is proposed in this paper. Current-steering diodes connected across the output chokes keep the inductor current continuous and retain the energy during the commutation period. The commutation time can thus be reduced to ensure a better welding performance. Also the stored energy can be released in the next energy transfer cycle to raise...
A new commutation method for a full-bridge current-source inverter is presented in this paper. During the commutation time, the four active switches are not simultaneously conducting. Instead, the two legs of the full-bridge inverter are in turn triggered on to provide the conducting paths for the load current. The steady-state load current can be reduced to zero during the commutation time. The residue...
