The search for solutions to the different power quality problems, in special the ones related to the voltage level compliance to the standard values has produced, up to now, an extensive range of commercial products using different techniques. Despite this recognition, the challenge for alternative strategies, presenting low cost and low maintenance properties, are very attractive and this subject is still motivating research worldwide. In this context, this dissertation is focused on the proposal of a voltage regulating device, here referred as CET (Electromagnetic Voltage Compensator), which presents an innovative design to obtain the process of voltage regulation. The main idea is based on the voltage injection, been as an additive or subtractive way, through a physical arrangement, presenting as a full electromagnetic power device. Aiming operative dynamic properties, the proposal in question, as far as their operational design concerns, is based on electronic switching and control device. The proposal outlined here will encounter emphasizes to the CET physical structure, the control unit composition and the evaluation of the electric complex performance under different voltage deviations occurrences. The studies are presented and then discussed, using the results provided by the computational simulation carried out in the time domain simulator ATP throughout its classical feature the MODELS language.
