Wave energy converters require a power conversion stage to convert the variable output from an electrical generator into a constant voltage and frequency for grid connection. To enable further development in grid integration of wave energy converter systems, this paper looks at the main power conversion considerations in converting wave energy into electrical energy and reviews current power converter topologies. In particular, the paper highlights the trade-off between energy storage, which brings about improved power quality, and improved reliability due to the absence of capacitors.
