High voltage generator for wind turbines

High voltage generator for wind turbines

Abstract

This paper proposes a high voltage hybrid generator (HG) for wind turbine application. The output of the HG is rectified to a DC-link. The HG employs a multiphase stator winding that improves power density while eliminating the DC-link capacitors at the machine rectified output. The HG has two rotor field excitations, namely permanent magnet (PM) and wound field (WF). The PM and WF elements of the HVHG rotor are mounted on the same rotor shaft and rotate at the same speed, thus the machine combined output voltage is due to a fixed field from the PM rotor and a controlled variable voltage due to the variable field from the WF rotor. Hence, the total output voltage is a controllable variable voltage, but over a limited voltage range.
