DETERMINATION OF INPUT/OUTPUT CHARACTERISTICS OF FULL-BRIDGE AC/DC/DC CONVERTER FOR ARC WELDING
This paper describes the design and practical implementation of AC/DC/DC converter in mode of arc welding. An analysis of the operation of AC/DC/DC converter and its input/output characteristics are determined with computer simulations. The practical part is con- sisted of AC/DC/DC converter prototype for arc welding with output power of 3 kW and switching frequency of 64 kHz. The operation of AC/DC/DC converter is validated with experimental measurements.
