A new topology is proposed for direct drive wind turbines that eliminates the use of the failure prone dc-bus electrolytic capacitor, avoids the need for a dc-link inductor by utilizing the synchronous inductance of the wind turbine permanent-magnet generator (PMG), and provides a low-voltage generator design, which decreases the amount of permanent-magnet material used in PMG, and reduces the volume...
In this paper, a new power electronics interface topology for Direct Drive Wind Turbines (DDWTs) to improve the system reliability and with a potential to decrease the size of the Permanent Magnet (PM) generator is presented. In the proposed topology the grid-side Voltage Source Converter in a traditional DDWT is replaced by a three-phase single-stage boost inverter. This enables the use of a low-voltage...
In this paper, a new generator-converter system for direct drive wind turbines in order to decrease the capital cost and improve the system reliability is presented. The grid-side Voltage Source Inverter (VSI) is replaced by a single-stage boost inverter. This provides flexibility to design a low-voltage generator and thus decreasing the number poles required in the generator. A 1.5MW generator for...
