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.

Selection of suitable PWM switching and control methods for modular multilevel converter drives /
Çiftçi, Barış; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2014)
The thesis focuses on the determination of suitable carrier based PWM switching and control method for modular multilevel converter drives. Characterization of various level-shifted and phase-shifted carrier based PWM methods are provided in terms of switching pulse patterns and resultant voltage waveforms both for N+1 and 2N+1 level output phase voltages. Modular multilevel converter PWM based control approaches are evaluated. Performances of different control methods are given for output harmonics distort...
Adaptive control of DC link current in current source converter based STATCOM for improving its power losses
Karaduman, Ferdi; Ermiş, Muammer; Bilgin, Hazım Faruk; Department of Electrical and Electronics Engineering (2012)
In conventional three-phase PWM (Pulse Width Modulation) current source converter based STATCOM (Static Synchronous Compensator) applications, DC link current is kept constant at a predefined value and the reactive power of STATCOM is controlled by varying modulation index. This control strategy causes unnecessary power losses especially when the reactive power of STATCOM is low. For this purpose, in order to reduce the active power drawn by STATCOM, the modulation index can be maximized by adjusting DC lin...
Common-Mode Voltage Reduction Pulsewidth Modulation Techniques for Three-Phase Grid-Connected Converters
Hou, Chung-Chuan; Shih, Chih-Chung; Cheng, Po-Tai; Hava, Ahmet Masum (2013-04-01)
This paper experimentally investigates the performance of three-phase voltage source pulsewidth modulation (PWM) converter, with the grid interfaced photovoltaic energy conversion system being the main application. In such applications the ground leakage current [common mode current (CMC)] should be much less than an ampere and this is difficult to obtain in transformerless (direct) connected systems. With the target being the reduction of the common mode voltage (CMV) and CMC, the converter performance is ...
Sliding Mode Control Of Permanent Magnet Synchronous Motor Fed By Wind Turbine Generator Taking Saturation Effect Into Account
Benchabane, F.; Titaouine, A.; Bennis, O.; Guettaf, A.; Yahia, K.; Taibi, D. (2011-09-10)
In this paper, we present the voltage build up process and the terminal voltage control of an isolated wind powered induction generator driven by a variable speed wind turbine using rotor flux oriented vector control. A description of the studied system is provided, and a simulation study is presented. The model used for the autonomous induction generator is a diphase one obtained by application of the Park transform. Theis model permits, when adopting some simplifying hypotheses, taking account the saturat...
