Linear generators have been proposed as a suitable power take-off system for direct drive wave energy conversion. Coupled directly to a reciprocating wave energy device, it is suggested that linear generators could be a viable alternative to hydraulic and pneumatic systems. This paper discusses the challenges involved in control of a direct drive wave energy converter, predominantly for maximum power extraction through electrical means. It highlights characteristics of linear generator control, particularly due to mechanical and electrical resonance, and the implications upon the power conversion stage. Results show that an overrated power converter is necessary due to the reactive power requirement for optimal control.
