FIELD: electrical equipment.
SUBSTANCE: invention relates to electrical equipment. Throttle is made toroidal with a sawtooth winding on the frame. 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 on the frame. Over the air gaps of each layer, magnetically conductive shunts of a soft magnetic material with a maximum initial magnetic permeability are installed.
EFFECT: technical result consists in increasing the load currents with increasing frequency of the supply voltage and reducing inductive and active losses.
