V300-PRO THEOR Y OF OPERA TION INPUT LINE VOL T AGE & AUXILIAR Y TRANSFORMER The V300-PRO can be connected for a variety of three phase or single phase input voltages. Power is applied through the Line Switch to the Input Rectifier and the Auxiliary T ransformer .
V300-PRO THEOR Y OF OPERA TION PRECHARGE & PROTECTION CIRCUITS The DC voltage from the Input Rectifier is applied to the Driver Board to begin charging the Switch Board capacitors at a slow rate. When the pre-charge level is achieved, the input relays close, applying the full DC voltage to the capacitors.
V300-PRO THEOR Y OF OPERA TION SWITCH BOARDS The Switch Boards contain the the Field Effect T ransistors (FET s) which, when switched ON, supply power to the primary windings of the main transformer . Each Switch Board powers a separate, oppositely wound primary winding.
V300-PRO THEOR Y OF OPERA TION OUTPUT AND CONTROL CIRCUITS The AC output of the transformer is changed to DC by the Output Rectifier . The Output Choke between the negative side of the rectifier and the negative output stud provides the necessary filtering for DC welding.
V300-PRO THEOR Y OF OPERA TION An FET is a type of transistor . FET s are semiconduc- tors well suited for high-frequency switching because they are capable of going from full off to full on much more quicklfy than other types of semi-conductors. Drawing A above shows an FET in a passive mode.
V300-PRO THEOR Y OF OPERA TION E-7 E-7 Return to Section TOC Return to Section TOC Return to Section TOC Return to Section TOC Return to Master TOC Return to Master TOC Return to Master TOC Return to Master TOC Since only 2 microseconds of the 50-microsecond time period is devoted to conducting, the output power is minimized.
