2003-2007, Power Electronics, Berlin University of Technology, Berlin, Germany.   Thesis: Investigation and Comparison of Multi-Level Converters for Medium Voltage Applications.   Abstract: The development of new high power semiconductors such as 3.3kV, 4.5kV and 6.5kV Insulated Gate Bipolar Transistors (IGBTs) and 4.5kV to 5.5kV Insulated Gate Commutated Thyristors (IGCTs) and improved converter designs have led to a drastic increase of the market share of PWM controlled Voltage Source Converters (VSC). Despite a price reduction of Gate Turn Off Thyristors (GTOs) by a factor of two to three over the last five years, also conventional GTO Voltage Source Converters and Current Source Converters (CSC) are increasingly replaced by PWM Voltage Source Converters with IGCTs or IGBTs in traction and industry applications. Today the two levels Voltage Source Converter (2L-VSC) applying IGBTs is clearly the dominating converter topology in traction applications that means low power-, medium power- and high power propulsion. The 2L-VSC offers technical advantages like a simple power part, a low component count and a straight forward protection and modulation scheme. On the other hand, the hard switching transients of the IGBTs at high commutation voltage cause high switching losses and a poor harmonic spectrum which cause additional losses in the machine. Further problems are caused by over voltages in cables and machines as well as bearing currents due to the steep switching transients. Multi-level converters enable a commutation at substantially reduced voltage and an improved harmonic spectrum. On the other hand the power semiconductor count is increased compared to 2L-VSC. The goal of the research is a detailed investigation of Multi-level converters for the next generation of traction converters. On the basis of the application requirements different Multi-level converters structures will be designed, simulated and evaluated. The development of new modulation and protection schemes and the investigation of the redundancy concepts are important tasks of the research. Finally the amount of active and passive components, the modulation, the protection scheme, efficiency of converter and machine, size, weight and costs will be calculated and compared to the state of the art 2L-VSC.   M.Sc.     1990-1993, Electrical Power Engineering, Iran University of Science and Technology, Tehran, Iran.   Thesis: Behaviour and Placement Studying of the Optimal VARS in the Distribution Networks.   Abstract: The capacitor compensation improve the electric power factor in the electric distributing networks. Consequently, the valence of the electric power generation, transmission, distributing substation and peripheral equipments are increased by the power factor improvement. This reduces the electric power and energy losses and also the network voltage falling and therefore, the distributing networks are efficiently operated with the low expenses. In this project, the problems of Volt-Ampere-Reactive (VAR) compensators are synchronously discussed which include such as defining of the capacitor installation location, values and optimal control analysis of the parallel capacitors, minimum number and location of the voltage feeders regulators and their control strategy. For the VAR compensators placement, the objective function is the peak loss reduction and the voltage profile placing in the authorized limitation.   B.Sc.     1986-1990, Electrical Power Engineering, Isfahan University of Technology, Isfahan, Iran.   Thesis: Design of 230kV Transmission Line between Abadan and Chelmile.
