INVERTER POWER SUPPLY FOR WELDING |
摘要 |
A high frequency power supply for supplying a welding current through a choke to a welding station including an electrode element and a workpiece element. The power supply includes a first transformer with a first core and means for receiving on said first core a first secondary winding with the first core being magnetized in a first flux direction upon creation of first current pulse and a second transformer with a second core and means for receiving on said second core a second secondary winding with said second core being magnetized in a second flux direction upon creation of a second current pulse in the direction opposite to the first pulse. The first transformer is operated by a first capacitor means for applying a first voltage to the first transformer upon operation of a first switch means and the second transformer is operated by a second capacitor means for applying second voltage to the second transformer upon operation of a second switch means. A single rectifier charges the first and second capacitor means to a given total voltage and control means are provided for maintaining said first and second voltages generally equal.
