ABSTRACT:
A transformer having a main winding and a control winding has a pair of E-shaped cores (10, 11), and an I-shaped third core (13) positioned on one E-shaped core (10). A small groove (14) is provided on the base plate (10c) of the first E-shaped core (10). A control winding (12) is wound on the I-shaped core (13) so that the winding (2) rests in the groove 14. Those cores (10, 11, 13) are made of ferrite material. Thus, both the main winding and the control winding can be produced using a winding machine.
