Development and Wave Tank Demonstration of a Fully Controlled Permanent Magnet Drive for a Heaving Wave Energy Converter

One option for converting the energy in sea waves into renewable electricity is development of floating wave converters coupled to electrical generators. For this work, bespoke slow-speed machines bidirectional power smoothing electronic are required. This paper reports on successful design and tank validation an electric machine, converter fully controlled direct drive take-off system two small scale heaving converters. The design, demonstration linear generators presented including some simulated laboratory results. Demonstration with pure drives, automated control, flow active force management almost unique essential future development. results prove that direct-drive devices technically possible can be used implement control both resonant non-resonant systems.
