“…In electrical engineering, it is essential to supply power to the wide variety of devices connected to the network, achieved by energy conversion [1]. The devices connected to the network range from domestic use lamps to more complex technologies such as electrical microgrids [2].…”

Diseño e implementación de un controlador digital tipo PID con pre-compensación para un Boost PFC de medio puente

“…La electrónica de potencia se ha vuelto parte fundamental de la infraestructura eléctrica actual, debido a que, siendo una rama de la ingeniería eléctrica, permite suministrar energía a la gran variedad de dispositivos conectados a la red con características particulares de funcionamiento. Esto se logra mediante la conversión de la energía disponible en los alimentadores a la forma de energía requerida por la carga [1], que pueden ser desde lámparas LED de uso doméstico a tecnologías más complejas como cargadores de baterías para sistemas fotovoltaicos [2], y micro redes eléctricas aplicadas a sistemas eléctricos inteligentes [3].…”
