Modeling a Linear Generator for Energy Harvesting Applications

Abstract

The intent of this research is to draw attention to linear generators and their potential uses. A flexible model of a linear generator created in MATLAB Simulink is presented. The model is a three-phase, 12-pole, non-salient, synchronous permanent magnet linear generator with a non-sinusoidal back electromotive force (EMF) but could easily be adapted to fit any number of poles or any back EMF waveform. The emerging technologies related to linear generators such as wave energy converters and free-piston engines are explained. A selection of these technologies is generically modeled and their results are discussed and contrasted against one another. The model clearly demonstrates the challenges of using linear generators in different scenarios. It also proves itself a useful tool in analyzing and improving the performance of linear generators under a variety of circumstances.
