  • A Novel Solid-State Transformer with Improved Flyback Converter Equipped with Quasi Z-Source Converter for Medium-Voltage Utility Grid 
    Cuma, Mehmet Ugras; Anvari, Alireze Deljavan; Savrun, Murat Mustafa (ENERGIES / MDPI, 2023-03)
    This paper introduces an enhanced solid-state transformer topology for a medium-voltage (MV) utility grid. The main objective of the current study is to develop an improved flyback converter equipped with a quasi z-source ...
  • Design and implementation of algorithms for one pedal driving in electric buses 
    Cuma, Mehmet Ugras; Unal, Cagla Dericioglu; Savrun, Murat Mustafa (ENGINEERING SCIENCE AND TECHNOLOGY-AN INTERNATIONAL JOURNAL-JESTECH / ELSEVIER, 2021-02)
    Nowadays, the interest in electric vehicles (EVs) is increasing in parallel with falling prices of batteries, developing battery technology and willing to reduce carbon emissions. However, the most important problem of EVs ...
  • DSP controlled voltage disturbance generator 
    Savrun, Murat Mustafa; Tan, Adnan; Koroglu, Tahsin; Cuma, Mehmet Ugras; Bayindir, Kamil Cagatay; Tumay, Mehmet (JOURNAL OF ELECTRICAL SYSTEMS / ENGINEERING & SCIENTIFIC RESEARCH GROUPS, 2018-03)
    Voltage disturbance generator (VDG) is a kind of device used to generate voltage disturbances that may occur in the network in order to test and evaluate the performance of the power quality devices such as Dynamic Voltage ...
  • Isolated H-bridge DC-DC converter integrated transformerless DVR for power quality improvement 
    Savrun, Murat Mustafa; Koroglu, Tahsin; Tan, Adnan; Cuma, Mehmet Ugras; Bayindir, Kamil Cagatay; Tumay, Mehmet (IET POWER ELECTRONICS / INSTITUTION ENGINEERING TECHNOLOGY-IET, 2020-04)
    This study presents a new H-bridge DC-DC converter-based transformerless dynamic voltage restorer topology (DVR). The proposed system can compensate balanced and unbalanced voltage sag/swell that are the most common ...
  • Performance Benchmarking of Active-Front-End Rectifier Topologies Used in High-Power, High-Voltage Onboard EV Chargers 
    Cuma, Mehmet Ugras; Savrun, Murat Mustafa (Çukurova Üniversitesi Mühendislik-Mimarlik Fakültesi Dergisi = Cukurova University Journal of the Faculty of Engineering / Çukurova Üniversitesi, 2021-12)
    High power onboard battery chargers employed in electric vehicles (EVs) and plug-in hybrid EVs (PHEVs) fed from three-phase mains typically consist of a two-stage structure as AC-DC and DC-DC stages. The AC-DC stage is ...
  • Prediction of Ultimate Tensile Strength of Prestressed Concrete Strand Using Artificial Neural Network Model 
    Cuma, Mehmet Ugras; Ozel, Hayrullah; Koroglu, Tahsin (Çukurova Üniversitesi Mühendislik-Mimarlik Fakültesi Dergisi / Çukurova Üniversitesi, 2018)
    The iron and steel industry is one of the essential sector for the industrial and economic development of a country. The most common problem in iron and steel industry is to determine the ultimate tensile strength of the ...
