A capacitive discharge (CD) welder includes a charging circuit, a capacitor bank, an insulated gate bipolar transistor (IGBT), a pulse transformer and a secondary circuit. The charging circuit takes incoming electricity and charges a capacitor bank. The capacitor bank stores energy. The IGBT electrically connects and disconnects the capacitor bank to the pulse transformer. The pulse transformer reduces voltage from that stored in the capacitor bank to the desired welding voltage. The secondary circuit electrically connected to the pulse transformer provides a welding current corresponding to the output to the material being welded.
Soudeuse à décharge capacitive (CD) comprenant un circuit de charge, une batterie de condensateurs, un transistor bipolaire à grille isolée (IGBT), un transformateur d'impulsions et un circuit secondaire. Le circuit de charge absorbe le courant et charge la batterie de condensateurs. La batterie de condensateurs assure l'accumulation d'énergie. Le transistor IGBT connecte / déconnecte électriquement la batterie de condensateurs au / du transformateur d'impulsions. Le transformateur d'impulsions réduit la tension disponible aux bornes de la batterie de condensateurs à une valeur correspondant à la tension de soudage requise. Le circuit secondaire est connecté électriquement au transformateur d'impulsions pour fournir un courant de soudage de sortie correspondant au matériau soudé.
