Planar transformer for energy harvesting applications

The paper is concerned with the numerical analysis of two designs of planar, miniature, flyback transformer (FBT) powered up by a pulse width modulated (PWM) voltage supply at high frequency. The first model uses a nonmagnetic medium for a part of the magnetic circuit, whereas the second design uses...

Summary:The paper is concerned with the numerical analysis of two designs of planar, miniature, flyback transformer (FBT) powered up by a pulse width modulated (PWM) voltage supply at high frequency. The first model uses a nonmagnetic medium for a part of the magnetic circuit, whereas the second design uses a magnetic nanofluid (MNF). The provided air gap in the central column of the ferrite core, which has the role of enhancing the stored magnetic energy, is varied. The thermal analysis accompanies this study.
