Progress in semiconductor technology in recent decades has been continuously innovative regarding renewable application. This paper presents fluctuationless output and increased energy captured by a permanent magnet synchronous generator (PMSG) based variable speed wind turbine system (VSWTS) through a composite action of peak power tracking (PPT) controllers in a closed-loop control of turbine speed and boost converter. Though the sensorless control of tip speed ratio (TSR) is preferred at most, incorporation of the high-speed digitized wind gauge replaces the complexity in the closed-loop drive of the turbine generator. The proposed concept includes control over solid-state converters (SSC) to eliminate switched-mode harmonics and thus DC link voltage is maintained at all levels. Fluctuations on the load side can be eliminated with a pulse width modulation (PWM) inverter. The circuit simulation proclaims PMSG voltage and boost voltage for different wind velocities to ensure real power control through optimal wind turbine speed and reactive power control through stabilized output voltage. Our investigation was performed on a 0.5 kW wind turbine generator and converter module to ensure the synchronized reactive power control at both SSC stages. Comparative test results were taken pertaining to the above discussion, which validates the performance of the proposed system in its typical area of application.
