Abstract

Induction coil is one of the key components of permanent magnet vibration-to-electrical power generator (VEPG). Here, the equivalent turn number of coil (ETNC) is introduced to build the relationship between the induction coil´s structure and magnetic field. And the dynamic magnetic flux density is calculated by finite element method (FEM). The optimized induction coil is fabricated according to the calculating result. The peak-to-peak voltage and effective value voltage of the optimized coil increase up to 52.59% and 48.76%, respectively, compared with the uniform coil.
