This paper assesses the feasibility three-phase PWM three-level voltage source converters (VSCs), namely NPC-type VSC (3L-NPC) and T-type VSC (3L-T) as alternatives to standard three-phase PWM two-level VSC (2L-VSC) for low-voltage grid interface applications, The topological performances are compared through a design algorithm regarding varying switching frequency, load condition, modulation index, and converter side inductance under distinct pulse-width modulation methods, Design of the LCL filter is also addressed, With the proposed design algorithm, a wide range of power levels (100kW-7MW) can be spanned and in the end the optimum topology and its design details are determined by comparing the return on investment (the pay-off time of total cost of ownership) of each design in the major energy markets.

Optimal Design of Grid-Connected Voltage-Source Converters Considering Cost and Operating Factors Kantar, Emre; Hava, Ahmet Masum (2016-09-01) This paper assesses the feasibility of three-phase pulse-width modulated (PWM) three-level voltage-source converters (VSC), namely neutral-point-clamped (3L-NPC) and T-type (3L-T) as alternatives to two-level converter (2L-VSC) for low-voltage multimegawatt renewable energy grid-connected converter applications. For this purpose, a novel design algorithm that takes switching frequency, capacity factor, modulation index, PWM scheme(s), and converter topology(ies) as input is unveiled to provide the design st...
Performance evaluation and comparison of low voltage grid-tied three-phase AC/DC converter configurations with SI and SIC semiconductor switches Öztoprak, Oğuzhan; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2019) In this thesis, as compared to silicon IGBT (Si-IGBT) technology, the advantages of using higher efficiency and faster wide bandgap silicon carbide (SiC) semiconductor switches in low voltage three-phase grid-tied PWM DC/AC voltage source converters (VSCs) are investigated in terms of sizing, efficiency and economic considerations for MW-scale photovoltaic power plant applications. As the cost and energy efficiency of a VSC strongly affect the total system economics, this thesis proposes a design methodolog...
Comparison of Two-Level and Three-Level NPC Inverter Topologies for a PMSM Drive for Electric Vehicle Applications Madan, Alican; Bostancı, Emine (2019-01-01) Multidimensional comparison of two-level and three-level DC/AC converters for a 120 kW permanent magnet synchronous machine (PMSM) drive is carried out in this study. Comparison of two topologies with Sinusoidal Pulse Width Modulation (SPWM) and Space Vector Pulse Width Modulation (SVPWM) by means of output current THD, conduction and switching losses, thermal stresses on semiconductors and switching frequency limitation are investigated at various operating points. Electro-thermal simulation of both topolo...
Design and implementation of a current source converter based active power filter for medium voltage applications Terciyanlı, Alper; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2010) This research work is devoted to the design, development and implementation of a Current Source Converter (CSC) based Active Power Filter (APF) for Medium Voltage (MV) applications. A new approach has been proposed to the design of the CSC based APF for reducing the converter kVA rating considerably. This design approach is called the Selective Harmonic Amplification Method (SHAM), and is based on the amplification of some selected harmoniccurrent components of the CSC by the input filter, and the CSC contr...
Design and implementation of a sic based three phase grid-connected current source inverter for solar applications Bay, Olcay; Ermiş, Muammer; Bilgin, Hazım Faruk; Department of Electrical and Electronics Engineering (2017) In this thesis, analysis, design and implementation of a three-phase 400V, 20 kVA Current Source Inverter (CSI) have been carried out for grid-connected photovoltaic applications based on the multi-string inverter concept. This inverter can be used in large scale photovoltaic (PV) applications by connecting many in parallel at 400V and coupling to medium voltage through a common transformer. The power stage of the inverter is based on the basic full-bridge CSC topology and each power semiconductor which mus...
