Abstract
In some examples, an isolation transformer can include a first wire having a first insulation thickness and a second wire having a second insulation thickness that is different than the first insulation thickness. The isolation transformer can further include a plurality of magnetic cores of magnetic material that can be configured to surround portions of each of the first and second wires along respective circumferences of the first and second wires to provide the isolation transformer.
Claims20
An isolation transformer comprising:
- a first wire having a first insulation thickness;
- a second wire having a second insulation thickness that can be different than the first insulation thickness;
- and
- a plurality of magnetic cores of magnetic material surrounding portions of both of the first and second wires along respective circumferences of the first and second wires.
A method for forming an isolation transformer, the method comprising:
- passing a loop forming portion of a primary side wire having a first wire thickness through a plurality of loop shaped magnetic cores;
- passing a loop forming portion of a secondary side wire having a second wire thickness through the plurality of loop shaped magnetic cores;
- and
- manipulating each loop forming portion of the primary and secondary side wires passed through the plurality of loop shaped magnetic cores to form respective primary and secondary side wire loop portions to provide the isolation transformer.
An isolation transformer that is free of a potting or an encapsulation material, the isolation transformer comprising:
- a primary side wire having a first insulation thickness defining a voltage isolation level for the isolation transformer from a primary electrical source or a load;
- a secondary side wire having a second insulation thickness that is different than the first insulation thickness, wherein the second insulation thickness of the secondary side wire defines a voltage isolation level of the isolation transformer from a secondary electrical source or the load;
- and
- a plurality of magnetic cores of magnetic material surrounding respective portions of each of the primary and secondary side wires along respective circumferences of the primary and secondary side wires.
