Abstract

We have investigated the power conversion and loss processes in magnetoelectric gyrators. Two types of loss mechanisms were identified by using a transformer-gyrator structure, which transfers power between magnetic and magnetomechanical forms. A missing portion of the power in a gyrator was then identified to be a returned power from the load resistor under low drive conditions. Under high drive conditions, decreases in both the magnetostriction and mechanical quality factor resulted in additional inefficiencies. Power transfer efficiencies of greater than 70% and 50% were achieved for magnetoelectric (ME) gyrators based on Metglas/Pb(Zr,Ti)O₃ laminated composites under low power drive and high power density drive (60 W/in.³) conditions, respectively.
