Optimization design of toroidal core for magnetic energy harvesting near power line by considering saturation effect

摘要: Recently, magnetic energy harvesting technologies have been studied actively for self-sustainable operation of applications around power line. However, lines has the problem saturation, which can cause performance degradation harvester. In this paper, optimal design a toroidal core harvesters proposed with consideration saturation near lines. Using Permeability-H curve and Ampere’s circuital law, optimum dimensional parameters needed to generate induced voltage were analyzed via calculation simulation. To reflect real environment, we consider nonlinear characteristic material supply current through 3-phase distribution panel used in industry. The effectiveness methodology is verified by experiments takes 60.9 V from line 60 A at Hz.Recently, Hz.
