Title:

TRANSFORMER

Document Type and Number:

Japanese Patent JP3535294

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To change a voltage, which is outputted in a secondary winding, with low control power by a method wherein a primary winding is wound on first and fourth column magnetic materials and the secondary winding and a control winding are wound on second and third column magnetic materials.
SOLUTION: A primary winding 21 is provided with series-connected winding parts 21a and 21b, both winding parts 21a and 21b are respectively wound on first and fourth legs 4 and 7 for the same number of turns so that magnetic fluxes, which are made to pass through the interiors of second and third legs (column magnetic materials) 5 and 6 in the opposite direction to each other, are respectively generated, a secondary winding 22 is provided with series- connected winding parts 22a and 22b and both winding parts 22a and 22b are respectively wound on the legs 5 and 6 in the opposite direction to each other and for the same number of turns. Moreover, a control winding 23 is provided with series-connected winding parts 23a and 23b and both winding parts 23a and 23b are respectively wound on the legs 5 and 6 in the same direction to each other and for the same number of turns.
