Abstract

The paper proposes a novel three-stage framework for rapid and reliable design optimization of complex impedance matching transformers for energy harvesting applications. Our approach involves inverse and forward surrogate modeling techniques. The inverse model is utilized to obtain a good initial transformer dimensions at the equivalent network modeling level. The forward surrogates (here, space mapping ones) permit rapid design closure at the full-wave EM simulation modeling level. The proposed methodology is demonstrated using a four-section compact transformer for energy harvesting applications. The circuit dimensions are scaled within wide ranges of the load impedance magnitude and phase (from 30 to 130 ohm and −26.5 to 26.5 degrees, respectively) at low computational cost corresponding to up to three EM analyses of the transformer structure. Reliability of the framework is validated through comprehensive numerical experiments as well as application case studies. The latter are provided to indicate that appropriate transformer design is critical for performance improvement of the rectifier circuits, both in terms of operational bandwidth and matching.

正、逆替代快速设计能量采集用紧凑阻抗匹配变压器
本文提出了一种新的三阶段框架,用于能量收集应用的复杂阻抗匹配变压器的快速可靠的设计优化。我们的方法包括反向和正向代理建模技术。利用逆模型在等效网络建模层面上获得了较好的初始变压器尺寸。正演代理(这里是空间映射代理)允许在全波电磁模拟建模级别快速完成设计。所提出的方法是用一个四节紧凑型变压器用于能量收集应用。电路尺寸在负载阻抗大小和相位(分别从30到130欧姆和- 26.5到26.5度)的宽范围内缩放,计算成本低,相当于变压器结构的三次电磁分析。通过综合数值实验和应用实例验证了该框架的可靠性。后者的提供表明,适当的变压器设计是关键的整流电路的性能改进,无论是在工作带宽和匹配方面。
