They have a simple structure, and are highly reliable and easy to maintain The use of a single main bearing structure to support the generator and wind rotor lessens the number of moving parts and further simplifies the structure The use of a shell main foundation optimises the load and simplifies operation and maintenance The use of programmable back-to-back DC-to-DC converter limits output noise Fitted with an internal electrical network with fault-tolerant function.
