1. energy storage device that is used for a transformer includes:

  • One first node is formed at the end on a former limit of this transformer;

    One Section Point is formed at the other end on this former limit;

    One the 3rd node;

    One resistance is coupled between this first node and the 3rd node;

    One diode, its anode connects the 3rd node, and its negative electrode connects first node;

    One first electric capacity is coupled between this Section Point and the 3rd node;

    AndOne clamp element is coupled between this Section Point and the 3rd node, is used for limiting the voltage at these first electric capacity two ends.
