Abstract
To provide a technology capable of restraining direct current magnetic deviation in a transformer without providing a gap in a core, an axis of easy magnetization is provided in a second direction intersecting with a first direction along a magnetic circuit of the core to thereby bring a B-H characteristic of a material characteristic of the core into an unsaturated state.
Claims8
A transformer comprising:
- a core for the transformer having an axis of easy magnetization in a second direction intersecting with a first direction along a magnetic circuit;
- and
- a primary side winding and a secondary side winding wound around the core for the transformer.
A transformer comprising:
- a core for the transformer in which a B-H characteristic of a magnetic circuit is brought into an unsaturated state;
- and
- a primary side winding and a secondary side winding wound around the core;
- wherein the transformer is operated in a region of the unsaturated B-H characteristic of said magnetic circuit;
- and
- wherein the core for the transformer has an axis of easy magnetization in a second direction intersecting with a first direction along the magnetic circuit.
