Abstract
PURPOSE: To reduce the size and weight of the reactor and simplify AC/DC switching, by constituting the secondary side of a transformer in a specified circuit comprising one reactor, four unidirectional control rectifier elements, and a changeover switch, and effectively utilizing the reactor in both AC and DC modes.
CONSTITUTION: First and second secondary output windings are constituted with first secondary output winding, control rectifier element (hereinafter referred to as element) 10b identical in the power feeding direction, reactor 3, welding load 4, and element 10a, and, similarly, a second half-wave control rectifier circuit is constituted with element 10d, load 4, element 10c, and reactor 3. When changeover switches 12, 13 are set to AC side, the output currents in said two circuits flowing alternately every half cycle will flow in the same direction in the reactor 3, and in reverse directions in the load 4. When the switches 12, 13 are set to DC side, the output currents in said two circuits flow in the same direction in the reactor 3 and load 4. At this time, two out of the four elements are used as diodes.
