Towards System-level Simulation of an Electromagnetic Energy Harvester Model via Equivalent Circuit Extraction from ANSYS Maxwell 3D

Abstract

Energy harvesting, a solution to provide a lifetime power supply to wireless systems, has attracted wide attention in the last decades. In this work, we will introduce the workflow of modeling an electromagnetic energy harvester model in finite element-based software ANSYS Maxwell 3D. Such a device converts kinetic energy into electrical energy. Then we will present the methodology of generating an equivalent circuit model and importing it into system-level simulation software ANSYS Twin Builder. The accurate and compact equivalent circuit model enables the interaction of the electromagnetic energy harvester model with both electrical and mechanical components.
