The journal which is a part of </span><a href="https://journals.evonexpublishers.com/"><strong>Evonex Publishers</strong></a><span style="font-weight: 400;">, is strategically positioned to make research and knowledge easily accessible to everyone. As a result, authors gain significantly greater audiences and visibility for their works. The extensive and all-inclusive focus of the African Journal of Applied, Natural and Earth Science makes it possible for academics to explore related subject areas.</span></p> https://journals.evonexpublishers.com/index.php/AJANES/article/view/30 2023-09-30T15:31:15+00:00 Iman Shirbandi Iman_shirbandi@juyandeganelm.ac.ir Armin Shirbandi ishirbandi@gmail.com Nilofar Shirbandi nshirbandi@gmail.com

<p><span style="font-weight: 400;">In the production and distribution of electricity, like anything else, there is a possibility of errors and some of these errors are unavoidable, such as having different voltage fluctuations. But these minor errors also increase the possibility of damaging the internal network system and even electrical appliances. Hence, a power transformer can make the oscillating input power become a non-oscillating output power. In some cases, the electricity consumption may suffer a severe drop, i.e. lack of voltage. In this case, having a transformer that increases in time means that the voltage improves and or&nbsp; voltage swell can compensate for the drop or sag, how important it is for us. However, by designing and using power electronic circuits and an&nbsp; fuzzy logical&nbsp; control system in the MATLAB software environment and by simulation, we can control these voltage fluctuations. We call this type of transformer application transformer voltage injection. Although based on the application, we can say that the transformer can be used as a power supply, impedance matching and voltage isolator and input and output.</span></p>
