Summary/Abstract: Welding current regulators are used in multi-station welding units, which are used in robotic welding complexes, for example when welding stator packages of electric motors, or large gas pipes in which it is simultaneously welded with 2-4 burners. The rapid development and implementation of inverter welding sources became possible after the development of suitable power transistors (JGBTs) and transistor modules. Multi-station welding sources have more power than conventional welding sources. This places higher demands on their energy performance, which requires very precise design and selection of the element base. The purpose of this article is to study the energy performance of transistor welding current regulators to obtain good energy performance.
