摘要： 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.
