Abstract

Un transformador eléctrico de impedancia variable bajo carga o no, que incorpora, en al menos una de sus fases de transformación, un primer y un segundo devanado auxiliar de variación de impedancia de polaridad magnética inversa, ambos devanados auxiliares divididos en módulos de circuito de impedancia y conectados en serie intercalando uno a uno sus módulos de circuito de impedancia, definiendo módulos de variación de impedancia que constan de tomas de impedancia configuradas para acoplarse eléctricamente a un selector de tomas escalonadas de impedancia controlado por un controlador de impedancia que permite variar la impedancia de la fase de transformación o del transformador eléctrico.
