Abstract

Improvements in the construction of transformers for switchable power supplies, especially for color television receivers, with a multi-column core, with at least one coil, made of ferromagnetic material, with at least one air gap, and otherwise It is magnetically closed, characterized in that only one column of the coil core, surrounded by the coil, has a gap and the winding that is on the gap is made of high frequency cable.
