Abstract

A transformer includes a ceramic housing, a primary winding disposed within the housing, a secondary winding disposed outside the winding, and a core extending through a first aperture in the housing. The housing includes a first portion and a second portion. Each of the first and second portions include a planar structure having a first housing aperture, and a plurality of sidewalls extending perpendicular to the planar structure along a plurality of edges of the planar structure. The first and second portions interface with one another when the ceramic housing is assembled such that the sidewalls of the first and second portions overlap with one another.

Claims (38)

1. A transformer comprising;

a ceramic housing comprising a first portion and a second portion, wherein each of the first and second portions comprise;

a planar structure having a first housing aperture and a second housing aperture; and

a plurality of sidewalls extending perpendicular to the planar structure along a plurality of edges of the planar structure;

wherein the first and second portions interface with one another when the ceramic housing is assembled such that the sidewalls of the first and second portions overlap with one another;

a primary winding disposed within the ceramic housing; a secondary winding disposed outside the ceramic housing;

and a core extending through the first housing apertures and the second housing apertures;

wherein the primary winding and the secondary winding comprise first and second winding apertures respectively that substantially align with the first housing apertures and the second housing apertures of the first and second portions of the ceramic housing.

2. The transformer of claim 1 , wherein the ceramic housing comprises aluminum oxide.

3. The transformer of claim 1 , wherein the primary winding is configured to be electrically coupled to an AC power source.

4. The transformer of claim 1 , wherein the secondary winding is configured to be electrically coupled to a load.

5. The transformer of claim 1 , wherein the primary and secondary windings comprise a substantially planar structure.

6. The transformer of claim 1 , wherein the core is of “U” shape, “I” shape, “L” shape or “O” shape.

7. The transformer of claim 1 , wherein the interior of ceramic housing is filled with an epoxy matrix.

8. The transformer of claim 7 , wherein the epoxy matrix includes one or more heat dissipation components.

9. The transformer of claim 1 , wherein the secondary winding comprises:

a first secondary winding portion disposed exterior to the first portion of the housing; and

a second secondary winding portion disposed exterior to the second portion of the housing, and electrically coupled to the first secondary winding portion.

10. The transformer of claim 9 , wherein each of the primary winding, the first secondary winding portion, and the second secondary winding portion are coupled to a circuit board.

11. The transformer of claim 10 , wherein the primary winding and the circuit board it's coupled to are both enveloped by the first and second portions of the housing.

12. The transformer of claim 9 , wherein a layer of kapton is disposed on either side of the first secondary winding portion, and the second secondary winding portion of the secondary winding.

13. A system, comprising;

an alternating current (AC) power source configured to output an AC signal; a transformer comprising:

a ceramic housing comprising a first portion and a second portion, wherein each of the first and second portions comprise:

a planar structure having a first housing aperture and a second housing aperture; and a plurality of sidewalls extending perpendicular to the planar structure along a plurality of edges of the planar structure;

wherein the first and second portions interface with one another when the ceramic housing Is assembled such that the sidewalls of the first and second portions overlap with one another;

a primary winding disposed within the ceramic housing and electrically coupled to the AC power source;

a secondary winding disposed outside the ceramic housing; and a core extending through the first housing apertures and the second housing apertures; and a load electrically coupled to the secondary winding; wherein the transformer is configured to:

receive the AC signal from the AC power source;

step up or step down a voltage of the AC signal; and

output the stepped up or stepped down AC signal to the load;

wherein the primary winding and the secondary winding comprise first and second winding apertures respectively that substantially align with the first housing apertures and the second housing apertures of the first and second portions of the ceramic housing.

14. The system of claim 13 , wherein the ceramic housing comprises aluminum oxide.

15. The system of claim 13 , wherein the secondary winding comprises:

a first secondary winding portion disposed exterior to the first portion of the housing; and

a second secondary winding portion disposed exterior to the second portion of the housing, and electrically coupled to the first secondary winding portion.

16. The system of claim 13 , wherein each of the primary winding, the first secondary winding portion, and the second secondary winding portion are each coupled to a circuit board.

17. The system of claim 13 , wherein the primary and secondary windings comprise a substantially planar structure.
