C - core topology for PM wind generators with non-overlap iron-cored stator windings

This paper presents the study of a C-core topology for direct-drive PM synchronous wind generators (PMSGs) with non-overlap iron-cored stator windings. Some of the most common challenges regarding wind energy converters are first considered, leading to the development of the C-core topology concept and the theory behind it. Results from the finite element (FE) simulations are presented and finally the C-core topology is implemented into a conceptual PMSG and compared, on a 300 kW power level, to a PM conventional synchronous generator manufactured locally.
