Modeling and Design of Permanent Magnet Vibration-to-Electrical Power Generator’s Induction Coil
The Equivalent Turn Number of Coil (ETNC) is proposed for induction coil design. Simulation results show that the vibration on the induction coil’s structure. The optimized coil is composed by two symmetry parts on the condition of sinusoidal vibration. The effective value of output EMF of optimized coil increases 51.39% than uniform coil’s. In the experiment, the optimized and uniform coils are fabricated with 600 turns and comparatively studied in the same vibration-to-electrical generator. The test results show that the peak-to-peak value and effective value of output EMF of the optimized coil can increase up to 52.59% and 48.76%, respectively, compared with the uniform coil.
