Current control of welding inverter using 32-bit microcontroller

Benjamín MARCINEK, Matej BEREŠ

This paper summarizes the elaboration of a master’s thesis entitled „Welding Inverter Utilizing a 32-bit Microcontroller,“ completed during the second winter semester.

The present work extends the findings of a previously published article entitled „Welding Inverter Using 32-bit Microcontroller,“ in which a welding inverter hardware was adapted to incorporate STM32 microcontroller and current mode control. The current paper focuses on the load testing of the inverter and addresses the identified issues. One such issue was mitigated through the integration of a Proportional Integral Derivative (PID) controller, followed by the inclusion of a comfort feature.

Keywords:  anti-stick, high power, PID controller, welding inverter
