Özet:

This thesis involves the PWM and control unit design and simulation for three-phase PWM converter widely used for grid-interface of renewable energy systems, motor drives, etc. The study involves selecting the LCL filter parameters, switching frequency, the PWM method, the cost-effective feedback controlled algorithm, etc. for the converter. The design is verified by means of detailed computer simulations. The study considers the normal and unbalanced grid conditions, which may occur in the grid operating conditions. Several power ratings and operating conditions are considered to provide a thorough performance evaluation of the designed system.
