Abstract
The winding of matrix transformers having multiple turn primary windings is made much easier, and the resulting transformer is much more consistent, if a “cellular” insert having a plurality of through holes is placed through each trough hole of the matrix transformer. Preferably, there is one hole in the cellular insert for each wire, though two or more wires can be placed in each hole. In one embodiment, insulating cellular inserts are placed through the entire length of the cellular transformer to guide and locate the primary windings. In another embodiment, each element of the cellular transformer has cellular inserts, and the elements are coupled together. In another embodiment, the cellular insert is a conductor and is part of the secondary circuit.
Claims6
A cellular transformer comprising
- at least a first magnetic core having at least a first through hole therein for receiving at least a first secondary winding having at least a first secondary turn and a primary winding having a plurality of primary turns, the at least a first secondary winding passing at least once through the at least a first through hole of the at least a first magnetic core so that a changing magnetic flux in the at least a first magnetic core may induce a secondary voltage therein,
- at least a first cellular insert passing through the at least a first through hole of the at least a first magnetic core having therein a plurality of through holes generally parallel to the at least a first through hole of the at least a first magnetic core for receiving the primary winding, and
- the primary winding being wound through the at least a first cellular insert and through the at least a first through hole of the at least a first magnetic core to induce a changing magnetic flux therein,
- such that the plurality of primary turns is distributed generally equally among the plurality of through holes in the at least a first cellular insert and
- the plurality of through holes in the at least a first cellular insert guides and supports the plurality of turns of the primary winding.
