Abstract
In this article, an exhaustive analysis of inverters used in arc welding applications is conducted, highlighting the implementation of resonant inverters connected in series with resonant tanks. These tanks are composed of passive elements and exhibit various topologies, with the series LCL and series-parallel CLL configurations being the most notable for this application.
Additionally, other studies are examined that, although not using resonant tanks, present inverters with different innovative topologies. This article provides a comprehensive overview of the various inverter strategies and configurations employed, emphasizing their advantages and challenges in the context of arc welding. The results and discussions presented offer valuable insights into current and future trends in the design of welding power sources, contributing to the advancement and optimization of this technology in industrial applications, with the aim of providing design references for the subsequent design and manufacture of highly efficient and reliable welding power sources.
Keywords: Direct current, Inverter, Power factor corrector, Resonant tank, Total harmonic distortion.
