HIGH-FREQUENCY TRANSFORMER Russian patent published in 2018 - IPC H01F30/16 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. Transformer is made as a toroidal one, from isolated from each other two windings – one on the frame, the other inside the walls and in the frame body. Middle of each winding is grounded. Toroidal core is made of separate layers of soft magnetic material with the greatest maximum induction and a narrow hysteresis loop with the same minimum thickness of each layer, embedded in cups, isolated from each other and from the winding of the transformer. Over the air gaps, magnetically conductive shunts are made of a soft magnetic material with a maximum initial magnetic permeability. Windings are made of shielded copper wire with fluoroplastic insulation.

EFFECT: technical result consists in increasing the load currents with increasing frequency of the supply voltage and reducing inductive and active losses.
