Abstract

Magnetic energy harvesting is a promising technology for a self-powered sensor, because it rarely depends on the weather condition. In order to increase the power density, maximizing the harvested power is important. In this paper, the analysis for power harvesting according to varying primary current is prevailed, and a new design guideline of primary voltage for maximizing harvested power is suggested. This analysis is distinct in that the effect of magnetizing inductance was taken into the consideration. To confirm the validity of this paper, the experiments were prevailed with a prototype of 4 ~ 7 Arms primary current.
