In order to reduce size and weight, alternatives have been implemented to scale voltage levels of the electrical network, maintaining high efficiency and low distortion. The purpose of this article is to present the results of the design and construction of an electronic transformer controlled by a microcontroller (μC). The characterization of a resonant transformer with a ferrite core was carried out, and simulations were developed with the real models of the electronic elements to validate the design stage. The prototype that switches to different frequencies with dead time of 2μs was built, obtaining as a result, an output signal of 12Vrms that operates for resistive loads that consume from 0 to 50W with an efficiency ( ) approximately 94%. The results show the viability of developing programmable electronic transformers, which unlike resonant electronic transformers, allow to work at any power value designed without depending on a load.
