FERYSTER
Switching transformers, chokes, coils and ferrite cores
About the manufacturer
FERYSTER is a Polish manufacturer of inductive components whose origins date back to 1991 in Iłowa. The company specializes in coils, chokes and switching transformers for power electronics, EMC filtering and electronic power supplies. In addition to standard catalogue products, a significant part of its activity is based on components manufactured to customer documentation or developed for a defined electrical and mechanical application.
The manufacturer works with magnetic components used in flyback, forward, push-pull and bridge converter topologies, as well as common-mode and differential-mode filters. Its portfolio also includes ferrite cores, bobbins, bases, housings and other elements required to build complete magnetic assemblies. This makes it possible to support both prototype development and repeatable production of dedicated transformers and chokes.
For custom designs, parameters such as core material and geometry, turns ratio, air gap, winding arrangement, insulation system and operating frequency can be adapted to the target circuit. This is especially important in isolated power supplies, where efficiency, leakage inductance, creepage distances and temperature rise must be considered together. FERYSTER combines component manufacturing with engineering know-how in magnetic design, making the brand relevant for industrial, lighting and power-electronics projects.
Applications
FERYSTER products are used wherever energy conversion, galvanic isolation and electromagnetic-noise reduction are important.
- flyback, forward, push-pull and bridge switch-mode power supplies.
- input and output power filters.
