A 3-Leg Inverter-Based High-Frequency Welding Power Supply Capable of AC 220 and 440-V Operation

In this article, a dc/dc topology is proposed for welding power supply that achieves a high conversion efficiency of over 94%, requiring ac 220 and 440 V operation. The secondary-side structure of the proposed topology is the same as that of conventional welding power supplies but the primary side c...
