A wind generator system with an integrated boost converter

This paper presents a wind generator system with an integrated boost converter. With the proposed concept, the phase inductances of the generator can effectively be used as the boost inductor, eliminating the need for a separate inductor that is used in conventional wind turbine systems. Two topologies that allow for the use of phase inductances as the boost inductor are presented. The performance of the proposed generator system is evaluated using a novel SmartBlade wind turbine, which consists of extendible blades and a custom made PM generator. Simulations and experimental evidence of a 1.5 kW prototype system are presented to demonstrate the viability of the proposed concept, which would be attractive for small scale wind turbine systems.
