A new technique to improve the linear generator designed for oceanic wave energy conversion

Abstract

In this paper a new technique is proposed to improve the performance of the linear permanent magnet generator (LPMG) which is basically a point absorber. This paper also represents analysis, design and simulation of a LPMG for improvement of oceanic wave energy conversion (WEC). Different output voltage, current and power waveforms of the conventional and proposed LPMG are analyzed, simulated and compared by MATLAB software by constructing mathematical models of WEC, LPMG and output stage. Various parameters like magnitude, wavelength and phase of oceanic wave are observed to make proper simulation by changing different parameters. It is applicable almost all of the point absorbers and offers the great advantage to get relatively more even power distribution which is a major concern for WEC.
