Abstract
Wave is one of the renewable resources that can replace non-renewable resources to reduce the Green House Gas (GHG) emission. Other than wave geographical location and condition, the electronics technical design and components used also plays an important role to maximize the capture of wave energy. DC-DC converter topologies have been widely used in power conversions. However, wave energy has no uniform pattern making the electricity energy generated by it is unclean. Furthermore, there is no small-scale converter specifically for pico-scale linear generator which require high static gain to capture wave energy. With the aim to improve the performance of energy conversion, this paper proposed a new converter design based on the existing topology which is modified SEPIC. The simulation for the two converters is performed to identify the percentage of performance improvement by using MATLAB Simulink software before fabricating a prototype. The comparison of experimental and simulation data for the converters is conducted and analysed in this paper to validate its percentage of error. From the results obtained, it is proven that the modification made from the existing topology improved significantly to the overall performance of the converter.
