FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical components of power frequency electronics for general industrial, special equipment and technologies of aerospace industry and can be used predominantly in modular low-profile frequency generators with programmatically adjustable characteristics at power from 20 kW to 2 mW and more for systems with precise, powerful, controlled and computer-controlled process. High-current frequency inductance choke includes coil, winding of which is made in the form of flat spiral. Flat spiral consists of sections and insulators. Each section is made in the form of alternating bands of steel and copper. Insulators are located in several sections from each other. As insulator, Imidoflex can be used.
EFFECT: technical result of claimed invention is to provide opportunity for device to operate in region of pulsed currents from amperes to tens of thousands of amperes with practically constant inductance of spiral inductance choke, possibility of frequency-dependent concentration of magnetic field along the optically transparent magnetic axis of spiral winding of throttle with parametric frequency filtering properties, reduction in coefficient of proximity, as well as reducing cost of device.
