Abstract :
This paper discusses a new patent pending rectifier system for direct-drive permanent-magnet wind generators. The basic idea is to use a generator with two sets of three-phase windings. One will be connected to a diode bridge rectifier and the other to an active rectifier (e.g. IGBT). The purpose of this new concept is to achieve maximum generator torque, which allows compact and cost-effective permanent-magnet generators, with a reliable and cheap rectifier.
