POWER TRANSFORMERS AND POWER INDUCTORS FOR LOW FREQUENCY APPLICATIONS USING ISOTROPIC COMPOSITE MAGNETIC MATERIALS WITH HIGH POWER TO WEIGHT RATIO

摘要

A transformer for low frequency applications of from 50Hz to 1000Hz is described. The transformer comprises a core having a cylindrical symmetry around a main revolution axis. The core is formed of a soft isotropic magnetic composite material composed of iron and resin. Windings are enclosed in the magnetic core and disposed about a central column of the magnetic core and magnetically coupled with the magnetic core. The core is formed by core sections. An inductor for low frequency applications, DC to 1000Hz of similar construction is also described, the inductor comprises a core having a cylindrical symmetry around a main revolution axis. The core is formed of a soft isotropic magnetic composite material composed of iron and resin. Winding is enclosed in the magnetic core and disposed about a central column of the magnetic core and magnetically coupled with the magnetic core. The core is formed by core sections.
