En este artículo se describe el procedimiento que permite diseñar un controlador para un convertidor Sepic de 2 kilovatios con elementos no ideales que puede ser usado en aplicaciones industriales. Se obtiene el modelo conmutado del convertidor a partir de los modos de operación, con este se construye el modelo en pequeña señal que permite obtener la función de transferencia necesaria para el diseño del controlador análogo, garantizado un tiempo de establecimiento de 25 ms. Se muestran los resultados de simulación usando MATLAB®/SIMULINK® alrededor del punto de operación realizando perturbaciones a la salida del convertidor y variaciones en el voltaje DC de entrada, evaluando el desempeño del sistema en el dominio temporal. Con el controlador diseñado se satisface la especificación de diseño para las resistencias internas de los inductores hasta 0.3 Ohmnios.
