We mentioned the different working principles of wave energy conversion systems (WECs). In this chapter, we revisit each of them in detail. We begin with the working principles that might be described today as “classic” or “conventional” (due to their being at the center of studies and having already been implemented in prototypes, sometimes more than 30 years ago). We would also like to indicate the usual technical solutions for the conversion of mechanical energy into electrical energy (referred to as power take-off (PTO)). We then present what appear to be new trends, with sometimes genuine innovations in comparison to the technologies that could be tested in the past.
