Abstract
We report the resonance voltage transformation effect of magnetoelectric particulate composite based transformers. The effect of transformer geometry and magnetoelectric composition was investigated to identify the range of transformation ratios. Pb(Zr0.52Ti0.48)O3 (PZT) was selected as the piezoelectric phase and NiFe1.9Mn0.1O4 (NFM), Ni0.8Zn0.2Fe2O4 (NZF), CoFe2O4 (CF) and Co0.6Zn0.4Fe2O4 (CZF) were selected as the magnetostrictive phase for fabricating the transformer. It was found that the composition PZT - 20 NZF with cylindrical geometry exhibits a high voltage gain of 11. The magnitude of voltage gain is directly correlated with the mechanical quality factor (Qm). The results reported here present the possibility of developing magnetoelectric transformer for both step-up and step-down applications.
