Anywhere voltage is required, inductors are used. High-frequency inductors are used in the form of power transformers for galvanic isolation in switch mode power supplies, as storage reactors in boost converters, or as current-compensated reactors for minimizing disruptions. BLOCK can deliver this in various designs: whether that be open, encapsulated, in a housing, with ferrite toroidal core, or nanocrystalline wound core.
