Abstract

PURPOSE: To control the firing phases of the electric power cntrol elements for the secondary windings of transformer to stabilize the output by providing auxiliary windings provided with phase control circuits to an electric power transformer, in an electric power source device for welding using multiphase AC as an electric power source.
CONSTITUTION: Auxiliary windings 3 are provided to an electric power transformer for welding having primary windings 1, and secondary windings 2, and using 3 phase AC, and a rectifier group 11 consisting of rectifiers DR1WDR3 is connected to the coil output terminals of the respective phases. A voltage divider 12 constituted of resistances R2, R3 is provided to the output side thereof. A series circuit group 13 consisting of the rectifiers DR4WDR6 and a load resistor 14 in series to this are connected to the output side of the coils of the respective phases of the windings 3, and further a phase control circuit 9 provided with a comparing arithmetic circuit 15 is connected. The voltage ratios divided by resistors R4WR6 in the respective phases of the group 13 and the load resistor 14 are prevented from exceeding the voltage dividing ratio of the voltage divider 12, and welding is accomplished by accurately controlling the firing phases of electric power control elements 4W6 and stabilizing the output for welding.
