Title (EN) HIGH-FREQUENCY TRANSFORMERS USING SOLID WIRE FOR WELDING-TYPE POWER SUPPLIES
(FR) TRANSFORMATEURS HAUTE FRÉQUENCE UTILISANT UN FIL MASSIF POUR ALIMENTATIONS ÉLECTRIQUES DE TYPE SOUDAGE
Abstract:
(EN) High-frequency transformers using solid wire for welding-type power supplies are disclosed. An example welding-type power supply transformer includes: a first coil assembly comprising a first plurality of turns of a first solid wire wrapped around a first bobbin to form a first single-layer primary winding, and a second plurality of turns of a second conductor over the first plurality of turns to form a first single-layer secondary winding; a second coil assembly comprising a third plurality of turns of a second solid wire wrapped around a second bobbin to form a second single-layer primary winding, and a fourth plurality of turns of the second conductor over the third plurality of turns to form a second single-layer secondary winding; and first and second cores disposed at least partially within the first and second bobbins.
(FR) L'invention concerne des transformateurs haute fréquence utilisant un fil massif pour des alimentations électriques de type soudage. Un exemple de transformateur d'alimentation électrique de type soudage comprend : un premier ensemble bobine comprenant une première pluralité de spires d'un premier fil massif enroulé autour d'une première bobine pour former un premier enroulement primaire monocouche, et une seconde pluralité de spires d'un second conducteur sur la première pluralité de spires pour former un premier enroulement secondaire monocouche; un second ensemble bobine comprenant une troisième pluralité de spires d'un second fil massif enroulé autour d'une seconde bobine pour former un second enroulement primaire monocouche, et une quatrième pluralité de spires du second conducteur sur la troisième pluralité de spires pour former un second enroulement secondaire monocouche; et des premier et second noyaux disposés au moins partiellement à l'intérieur des première et seconde bobines.
