    Filtro Armónico Activo
    (2025-05-13) Di Lazzaro,, Ángel Gabriel; Dolaz, Leandro Agustín; Ubiedo, Lautaro Ezequiel; Chort, Agustín, Ing.
    Realizamos un prototipo de filtro armónico activo monofásico en derivación. El mismo funciona junto con una aplicación de visualización desarrollada en Python. Midiendo en tiempo real la corriente de carga mediante la placa de desarrollo Raspberry Pi Pico y el sensor de corriente SCT-013, ingresamos estos datos a un filtro adaptativo implementado en la FPGA Tang Nano 9k para generar, mediante un inversor de puente completo, los armónicos de la corriente de carga en contrafase, es esta señal la que se suma a la corriente de carga para disminuir la distorsión total armónica de corriente (THDi). La implementación de este prototipo, escalable en potencia y trasladable a tres fases, logró mantener un THDi resultante por debajo del 5 % de forma constante al usar como prueba una corriente generada por un dimmer y una carga resistiva con un THDi mayor al 70 %, e incluso realizando variaciones de la carga en tiempo real.

    Virtual Reality Technologies: Analysis of their Application in Electronics Engineering Career Programs.
    (2021-12-02) Perissutti, Gianfranco Adriano; Ubiedo, Lautaro Ezequiel
    Abstract: Many problems have arisen in traditional electronics engineering education because of the Coronavirus lockdown. Although these problems have not been solved yet, this paper analyzes the use of virtual reality (VR) technologies as a possible teaching resource to solve them. Even though VR devices are relatively new in the field of teaching, this analysis makes use of numerous research projects, weighing up its positive effects and its drawbacks. Summarizing the results, it is clear that hybrid learning (by means of conventional and virtual reality systems) presents some advantages to traditional learning. However, more research has to be done in order to evince these new devices as an improvement in engineering education.
