## Abstract

The conversion of energy is a fundamental aspect for adequate use of energy resources; thus, counting on appropriate devices and methodologies in education and research is essential. This document presents an experimental module for teaching and research on silicon controlled rectifiers (SCRs) in power systems, where different experiments designed to cover a diverse range of complexities are also proposed. In low complexity, the experiments focus on implementing phase control rectifiers and three-phase AC–AC voltage controllers, with particular attention to passive loads. On the other hand, in the field of high complexity, the experiments delve into the application of full-wave phase control three-phase rectifiers in direct current transmission systems, as well as the use of AC–AC voltage controllers in static reactive power compensators. The results show that the desired behavior is achieved according to the theory for the different experiments proposed.
