Abstract :
This paper presents mathematical modeling and numerical simulation results for a notional miniature power electrical transformer (MPST) with planar, spiral coils, fabricated in micro-electromechanical MEMS technology. The magnetic core of the MPST is partially made of custom-tailored magnetic nanofluid. The electrical circuit lumped parameters are computed from numerical simulation results based on 2D and 3D models. Finally, the magnetization body forces occurring in the fluid core are computed and the 3D motion that they produce is evidenced to be very slow.
