| Abstract |
In this paper, a sensorless control of PMSG(Permanent Magnet Synchronous Generator) for small wind turbine systems, which is based on stator flux and back-emf estimation. Also, a cost-effective AC/DC/AC converter that consists of a two-leg three-phase PWM converter and a half-bridge PWM converter is used for vector control of PMSG, which is impossible with the conventional diode-rectifier type converter. A sensorless control algorithm can eliminate pulse encoders for speed measurement, which reduces the system cost. Using PSIM simulation, the validity of the converter control performance and MPPT control of PMSG have been verified. |
