Design of Magnetic Cores for Current Transformer energy harvesting devices

The magnetic core is a determinant for the performance of the CT (current transformer) energy harvesting devices. In that case, a magnetic core power output model was established for accurately designing the magnetic core of the energy harvesting devices. Also, comparative verification was also performed through experiments. The effectiveness of the design scheme proposed in this paper was proven by experimental results after quantitatively analyzing the influence of air gaps on the core performance, comparing three core materials and analyzing their scopes of application, as well as proposing the principle of core design under different applications.
