Abstract
A generator assembly including generator means and a first converter member (), the generator means being arranged to convert mechanical power to electric power and comprising an AC generator (), a voltage regulator () and an AC coupling, the voltage regulator () being arranged to regulate magnetization of the AC generator () on the basis of data associated with the voltage of the AC coupling of the generator means, the AC coupling being arranged to supply electric power from the AC generator () to the first converter member (), and the first converter member () being arranged to rectify the voltage applied through the AC coupling into DC voltage. The first converter member () is arranged to adjust the power of the AC generator () by changing the component (I q) associated with the torque of the current passing through the AC coupling so as to provide the power of desired magnitude.
