CPC H01F 27/34 (2013.01) [H01F 27/28 (2013.01); H01F 38/08 (2013.01)] | 5 Claims |
1. A leakage transformer configured for a resonant converter, comprising:
a first plate and a second plate;
a plurality of winding pillars disposed on the first plate;
a primary winding and a secondary winding wound around the plurality of winding pillars; and
a plurality of magnetic shunt elements disposed on the first plate,
wherein one of the plurality of winding pillars and one of the plurality of the magnetic shunt elements are line-aligned in a first direction, the other one of the plurality of winding pillars and the other one of the plurality of the magnetic shunt elements are line-aligned in a second direction, and the first direction is in parallel to the second direction,
wherein a gap is located between the magnetic shunt element and the second plate, and a leakage inductance of the leakage transformer is determined by the gaps,
wherein a plurality of magnetic shunt elements are arranged in a first line, and a plurality of winding pillars are arranged in a second line, and the first line is parallel to the second line,
wherein a gap between the winding pillar and the second plate is configured for disposing a magnetizing inductance.
