Title (EN) GENERATOR FOR ARC WELDING MACHINES
(FR) GENERATEUR POUR MACHINES A SOUDER A L'ARC
Abstract: front page image
(EN)A generator for arc welding machines provided with an input rectifier stage (101) which has a unit power factor and comprises an inductor (107), on the main side, two diodes (109, 110) and two electronic switches (111, 112), one for each diode, which are driven by a driver which renders the absorption of the input rectifier stage practically sinusoidal.
(FR)L'invention concerne un générateur pour machines à souder à l'arc avec un étage de redressement (101) ayant un facteur de puissance unitaire et comprenant un inducteur (107) sur le bord principal, deux diodes (109, 110) et deux commutateurs électroniques (111, 112), un pour chaque diode commandés par un étage d'attaque qui fait en sorte que l'absorption de l'étage de redressement de l'entrée soit pratiquement sinusoïdale.
