Design and Implementation of a 300A Modular Welding Inverter

Abstract

Welding machines are one of the most important application areas of power electronics. Controlling the fast dynamics of these machines while keeping the efficiency high is a challenging task. Several topologies and control methods have been proposed in the literature. This paper presents a modular structure for a 9.6 kW welding inverter. The design process is explained in detail. Simulation and experimental results are provided to show that the proposed system can be a viable solution.
