A Magneto-Electric (ME) gyrator with a superior power efficiency of 95 % has been achieved based on a two-phase solid-state ME laminate. This ME gyrator consists of a winding coil that generates a magnetic field as the first step to realize electromagnetic energy transfer. A magneto-electric composite, serving as the second step, then converts the power from magnetic to electric forms. The laminate consists of two iron-cobalt based amorphous alloy layers bonded to a lead zirconate titanate plate. It has a giant magneto-electric coefficient of around 2200 (V/cm)/Oe at its mechanical resonant frequency (≈ 44 kHz) in structure. Approaching methods based on maximum power transfer (MPT) efficiency theory and the equivalent loss factor (ELF) from the input port have been introduced to evaluate the power efficiency of the ME gyrator. The expected MPT efficiency is 96.5 % at a power volume density of 0.1 W/in³ (6.1 mWatt/cm³), and 93.2 % up to 20 W/in³ (1.22 W/cm³). The ELF explains that the magnetomechanical conversion efficiency is related to the volume of the magnetic phase which is the dominating term in the power efficiency.

基于两相固态ME层压板，已经实现了具有95％的出色功率效率的磁电（ME）回转器。该ME回转器由一个绕组线圈组成，该绕组线圈会产生磁场，这是实现电磁能量传递的第一步。然后，作为第二步骤的磁电复合材料将功率从磁形式转换为电形式。层压板由两层铁钴基非晶态合金层组成，这些层粘结到钛酸锆钛酸板上。在结构上的机械共振频率（≈44 kHz）下，它具有约2200（V / cm）/ Oe的巨大磁电系数。引入了基于最大功率传输（MPT）效率理论和来自输入端口的等效损耗因子（ELF）的接近方法，以评估ME回转器的功率效率。³（6.1 mWatt / cm ³）和93.2％的最高20 W / in ³（1.22 W / cm ³）。ELF解释说，机电转换效率与磁相体积有关，磁相体积是功率效率中的主要术语。
