Abstract
The invention is applicable to the technical field of a transformer and provides a multi-magnetic-path transformer. The multi-magnetic-path transformer comprises eight magnetic paths formed by eight magnetic cores; a first winding is arranged on a first magnetic path and a second magnetic path; a second winding is arranged on a fourth magnetic path and a fifth magnetic path; a third winding is arranged on a seventh magnetic path and an eighth magnetic path; a third magnetic path is arranged between the first winding and the second winding; a sixth magnetic path is arranged between the second winding and the third winding; each of the first winding, the second winding and the third winding comprises a primary winding and a secondary winding; the first winding and the third winding are double-magnetic-path windings; the second winding is a single-magnetic-path winding. One magnetic path is respectively arranged between every two of the three windings so that mutual inductance does exist among the first winding, the second winding and the third winding; and three transformers are independently formed by the three windings, so that input and output of various different signals are realized and the function of the transformer is expanded.
