Abstract
According to one embodiment a transformer that includes a core having a central arm and first and second outer arms on opposite sides of the of the central arm, a primary winding surrounding the central arm and a secondary winding surrounding the central arm is disclosed. The transformer further includes a primary winding casing surrounding the primary winding, a secondary winding casing surrounding the secondary winding, and at least two spacers including a first spacer and a second spacer. The first spacer is configured and arranged to space the primary winding casing away from a bottom of the core and the outer arms and the second spacer is configured and arranged to space the secondary winding casing away from the primary winding casing and the outer arms.
Claims17
A transformer comprising:
- a core having a central arm and first and second outer arms on opposite sides of the of the central arm;
- first and second primary windings surrounding the central arm;
- a secondary winding surrounding the central arm;
- a primary winding casing completely surrounding the first and secondary primary windings, the primary winding casing including a primary conductive shield layer disposed on an inside of the primary winding casing that reduces electromagnetic interference;
- a secondary winding casing completely surrounding the secondary winding, the secondary winding casing including a secondary conductive shield layer disposed on an inside of the second winding casing that reduces electromagnetic interference;
- at least two spacers including a first spacer and a second spacer wherein:
- the first spacer is configured and arranged to space the primary winding casing away from a bottom of the core and the outer arms;
- and
- the second spacer is located between the primary winding casing and the secondary winding casing is configured and arranged to space the secondary winding casing away from the primary winding casing and the outer arms.
A method of forming a transformer, the method comprising:
- providing a bottom portion of a core having a central arm and first and second outer arms on opposite sides of the of the central arm;
- forming first and second primary windings;
- forming a second winding;
- disposing the first and second primary windings in a first winding casing including a first winding casing conductive shield layer disposed on an inside of the first winding casing that reduces electromagnetic interference, wherein the first winding casing completely surrounds the first and second primary windings;
- disposing the second winding in a second winding casing including a second winding casing conductive shield layer disposed on an inside of the second winding casing that reduces electromagnetic interference, wherein the second winding casing completely surrounds the second winding;
- placing a first spacer on the bottom portion of the core;
- disposing the first winding casing on the first spacer;
- placing a second spacer on top of the first winding casing;
- and
- disposing the second winding casing on the second spacer.
