Özet:

This thesis involves design and simulation for switch mode converter based damping of three-phase LCL-filtered PWM converter widely used for grid-interface of renewable energy systems. The study involves the resonance damping of high power voltage source converters connected to the grid via LCL filters. The design is verified by means of detailed computer simulations. The study considers eliminating the resonant harmonics which results in overvoltage/current stresses and leads to the failure of the converter. Several power ratings and operating conditions are considered to provide a thorough performance evaluation of the designed system.
