Abstract

La presente invención se refiere a un aparato que incluye un circuito magnetizante configurado para ser acoplado a un transformador y para proporcionar selectivamente una corriente magnetizante al transformador y un circuito de control configurado para causar que el circuito magnetizante proporcione la corriente magnetizante después de la desconexión del devanado primario del transformador a partir de la fuente de energía. El circuito magnetizante puede ser configurado para proporcionar la corriente magnetizante a partir de una primera fuente después de la desconexión del devanado primario a partir de una segunda fuente. El transformador puede incluir un primer transformador y el aparato puede incluir además un segundo transformador de impedancia superior acoplado entre la segunda fuente y el primer transformador. En modalidades adicionales, el circuito magnetizante puede incluir un convertidor de estado sólido.
