“…Another possible drawback is a significant current harmonics in capacitor C1 and in corresponding transformer winding W3 [5]. In the case of rectangular shape voltage the 3rd harmonic component is about 30% that also supports increasing of 3rd current harmonic.…”

“…There is known one such uncontrolled AC/DC converter with parallel and series resonance alternation (PSA) having a constant-power operation zone in its output characteristics [5]. This converter operates at mains frequency (50 or 60 Hz) and includes capacitor and inductor in resonant tank circuit.…”

“…The missing feedback reduces current oscillations during transients due to the parametrical variation of resonant tank topology that could take place up to six times of supply frequency [5]. And it corresponds well to good performance arc welding power source that requires the alteration between the modes can be as fast as possible [7].…”

Energy growing demand and environmental issues put more emphasis on optimal energy useby equipment and in process. In this paper a novel switch-mode load-resonant welding power source with output characteristic having constant power range is suggested. Due to the constant power operation and parametrical arc stability during manual welding process the better electrical and thermal performance and even weld bead could be obtained. The circuit of the suggested converter and criteria for its resonant components selection are given in order to describe proposed topology in relation to load conditions during welding. Theoretical and practical studies are conducted on experimental setup and first promising results have been obtained for given converter that are briefly presented and discussed.
