Design and Implementation of a MHz Frequency Transformer with a Ferromagnetic Fluid Core

Design and optimization of a magnetic fluid cored transformer are studied for high frequency applications. An easy cheap core is designed used to decrease the eddy current loses, thereby low conducting paramagnetic features added. The exhibits both solid characteristics exerting modes in due iron powder inside. finite element analysis simulations performed via COMSOL Multi-physics package different mass fractions powder. maximum peak-to-peak voltage power found as 526 mV 188.8 mW at 12 MHz from simulations. 3D patterns prove that flux magnetization exhibit turbulence core, localized values indicate an arbitrary attitude various frequencies. Optimum fraction 0.7, which parallel with experimental results. operates between 11 13.5 optimally.
