对7种不同的小型化低功耗隔离变压器拓扑结构进行了有限元仿真分析。对不同运行频率和运行高度、有无磁芯的固定区域变压器进行了性能优化。优化结果的比较揭示了不同拓扑结构在不同约束条件下的性能潜力和权衡。对于几种不同的拓扑，在$\mathbf{1}\\Text{mm}^{2}$的占地面积内，可以以超过85%的效率实现超过1 W的功率传输。
Seven different miniaturized low-power isolation transformer topologies are analyzed using FEA simulation. Performance optimizations of fixed-area transformers with different operation frequencies and heights, with and without magnetic cores, are performed. The comparison of optimization results reveals performance potential and trade-offs of the different topologies under different restrictions. More than 1 W of power transfer is possible at more than 85% efficiency in $\mathbf{1}\ \text{mm}^{2}$ of footprint area for several different topologies.
