HIGH-FREQUENCY TRANSFORMER RING-FIRED RING FERROMAGNETIC CORE

摘要

1. An annular ferromagnetic core of a high-frequency transformer extended along the cylinder axis, characterized in that two parts with a minimum and maximum level of the external field induced in them are distinguished in the core along the length of the core, on which additional windings are connected, interconnected in series and with a ratio of numbers turns in them are inversely proportional to the magnetic resistances of these parts of the core along the axis of the cylinder. 2. An annular ferromagnetic core according to claim 1, characterized in that each part of the core is divided in length into two parts, on which additional windings are connected, interconnected counter-sequentially, with the ratio of the number of turns in them inversely proportional to the magnetic resistances along the cylinder axis of these parts core.
