1. A DC transformer comprising:

  • a magnetic core comprising a first leg, a second leg having a first air gap, and a third leg having a second air gap;

    a primary winding wound around the magnetic core;

    a first secondary winding wound around the first leg and the second leg for generating a first inductance by the first air gap of the magnetic core; and

    a second secondary winding wound around the first leg and the third leg for generating a second inductance by the second air gap of the magnetic core, wherein the number of windings of the first secondary winding wound around the first leg is more than the number of windings of the first secondary winding wound around the second leg, and the number of windings of the second secondary winding wound around the first leg is more than the number of windings of the second secondary winding wound around the third leg.
