  1. 16. Techno-economic analysis of retrofitting existing fuel stations with DC fast chargers along with solar PV and energy storage with load flow analysis

    University essay from KTH/Energiteknik

    Author : Nilanshu Ghosh; [2020]
    Keywords : Electric vehicle charging; DC fast chargers; Load flow analysis; EV charging stations; CIGRE LV networks; Elfordonsladdning; DC-laddare; Lastflödesanalys; EV-laddstationer; CIGRE LV-nätverk;

    Abstract : The increasing number of electric vehicles (EVs) in the transport sector has rendered the conventional fuel-based vehicles obsolete along with the fuel filling stations. With the growth in EVs, there has been an increase in the public charging infrastructure with fast charging equipment being used to charge the EVs in least possible time and also address the issue of ‘range anxiety’ among the EV owners.

  3. 17. Isolated Single-Stage Interleave Resonant PFC Rectifier with Active and Novel Passive Output Ripple Cancellation Circuit

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Abidemi Oluremilekun Eleyele; [2020]
    Keywords : single-stage AC DC converter; bridgeless power factor correction PFC rectifier; active passive ripple cancellation; zero current switching ZCS ; zero voltage switching ZVS ; Electric vehicle EV charger; LLC;

    Abstract : With the increasing demand for fast, cheaper, and efficient power converters come the need for a single-stage power factor correction (PFC) converter. Various single-stage PFC converter proposed in the literature has the drawback of high DC bus voltage at the input side and together with the shift to wide bandgap switches like GaN drives the converter cost higher.

  4. 18. Filter Design for an HVDC protection IED

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Evgeny Genov; [2020]
    Keywords : ;

    Abstract : A selective fault detection approach is necessary for successful implementation of multi-terminal high-voltage direct-current (HVDC) grids. Fault detection is per- formed by an intelligent electronic device (IED) that takes in voltage and current measurements, performs fault detection algorithms, and outputs, e.g. READ MORE

  5. 19. SiC MOSFET function in DC-DC converter

    University essay from Uppsala universitet/Elektricitetslära

    Author : Christian Al Kzair; [2020]
    Keywords : SiC; Buck converter; Buck; Silicon carbide; ROHM;

    Abstract : This thesis evaluate the state of art ROHM SCT3080KR silicon carbide mosfet in a synchronous buck converter. The converter was using the ROHM P02SCT3040KR-EVK-001 evaluation board for driving the mosfets in a half bridge configuration. READ MORE

  6. 20. Comparison between Active and Passive AC-DC Converters For Low Power Electromagnetic Self-Powering Systems : A theoretical and experimental study of low power AC-DC converters

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Ibrahim Hamed; [2020]
    Keywords : Energy-harvesting; electromagnetic; rectifiers; AC DC-converters; Active voltage doublers; Passive voltage doublers.;

    Abstract : Electromagnetic based energy harvesting systems such as Variable reluctance energy harvesting systems (VREH) have shown to be an effective way of extracting the energy of rotating parts. The transducer can provide enough power to run an electronic sensing system, but the problem arises in finding an efficient way of rectifying that power to generate a stable energy supply to run a system, which this report will investigate.
