Abstract
There is provided a transformer improved in leakage inductance including: a core having first, second and third legs electromagnetically coupled to one another; a primary winding formed of a conductor having one end and another end receiving power from the outside and dividedly wound around the first, second and third legs; and a secondary winding wound around at least one of the first, second and third legs and receiving induced power by electromagnetic induction with the primary winding.
Claims1
A transformer having improved leakage inductance comprising:
- a core having first, second and third legs electromagnetically coupled to one another;
- a primary winding formed of a conductor having one end and another end for receiving outside power and dividedly wound around the first, second and third legs, respectively;
- and
- a secondary winding wound around at least one of the first, second and third legs and receiving induced power by electromagnetic induction with the primary winding;
- wherein the core has the first leg formed at one side thereof, the second leg formed at another side thereof to be electromagnetically coupled to the first leg, and the third leg formed between the first and second legs to be electromagnetically coupled to the first and second legs;
- wherein in the primary winding dividedly wound around the first, second and third legs, turns of the primary winding wound around the first leg are identical in number to turns of the primary winding wound around the second leg;
- and
- wherein the secondary winding is dividedly wound around the first and second legs, respectively.
