Abstract
A zero-sequence blocking transformer includes a first core part, a first pair of windings wound around the first core part, a second core part and a second pair of windings wound around the second core part, the first core and the second core having a geometry to generate a leakage inductance.
Claims4
A zero-sequence blocking transformer comprising:
- a single core defining a closed magnetic path around which at least six windings are wound, the single core having:
- a first core part;
- a first pair of the four windings wound around the first core part;
- a second core part;
- a second pair of the four windings wound around the second core part, the first core and the second core;
- a third core part;
- a third pair of windings wound around the third core part;
- wherein the first, second and third core parts combine to form the single core;
- and
- wherein the single core further include leakage core part connected in parallel with the first, second and third core parts and around which no windings are wound.
