Comparison of Direct Drive Hydraulic and Permanent Magnet Linear Generator Machines for Ocean Wave Energy Conversion
Recently, there have been peaked interest in developing high energy producing and optimized power take-off topologies for Wave Energy Converters (WEC). As large as the potential of the oceans may seem, harnessing that energy and effectively converting it to electricity in significant amounts is a challenge. Currently, there are no single devices that satisfy this sufficiently.

We compare two promising Power Take-Off (PTO) units; the Permanent Magnet Linear Generator (PMLG) and the Direct Drive Hydraulic Power Take-Off (DDHPTO). A steady state and transient analysis is done to compare the efficiencies of the two machines. The results will show that the PMLG has the higher efficiency and a greater Annual Energy Production (AEP) over the DDHPTO.
