Abstract
An isolation transformer comprises two core pieces mounted to cooperate to provide flux paths, one of the core pieces being shaped so that a central flux path is defined by a central leg of the core, at least two magnetically coupled windings surrounding the central flux path, and an isolation layer sandwiched between the windings.
Claims16
An isolation transformer comprising
- two E-shaped core pieces mounted to cooperate to provide flux paths, one of the core pieces having a leg defining a portion of one of the flux paths,
- at least two magnetically coupled windings surrounding said one of the flux paths, and
- an isolation layer located between the windings and between the leg of one of the core pieces and the other core piece.
An isolation transformer comprising:
- a first E-shaped core piece having a central leg;
- a second E-shaped core piece having a central leg mounted to cooperate with the central leg of the first E-shaped core piece to provide a central flux path;
- at least two magnetic ally coupled and free standing bondable windings surrounding the central flux path;
- and
- an isolation layer formed from a single integrated sheet, the isolation layer located between the windings and between the leg of one of the core pieces and the other core piece, the isolation layer including adhesive on one side and contacting at least one of the central legs.
