Northern Power Systems' Northwind 100 wind turbine uses a digital drivetrain to deliver 100 kW of rated power. Leveraging SHARC processors, data converters and other ADI components, the Northwind 100's permanent magnet direct drive (PMDD) design eliminates the need for a gearbox by replacing it with a full power converter, according to ADI.
ADI's 32-bit floating point SHARC 21363 digital signal processor hosts real-time closed-loop control algorithms to efficiently control the Northwind 100's generator and power converter subsystems, according to the company.
SHARC 21363 processors employ an enhanced single instruction, multiple data architecture to provide the real-time processing bandwidth and atomicity required to keep these subsystems running in precise coordination, the company adds.
