1. 21. Study of an Isolated and a Non-Isolated Modular DC/DC Converter : In Multi-Terminal HVDC/MVDC grid systems

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

   Author : Ranjithh Raj Ram Prakash; [2019]
   Keywords : High power high voltage DC-DC converter; Isolated non-isolated DC-DC converter; HVDC MVDC interconnection; HVDC HVDC point-to-point link; Modular multilevel converter; Transformer driven MMC; Steady state transient DC fault analysis; High Power DC DC-omvandlare med hög spänning; Isolerad och icke-isolerad DC-DC-omvandlare; HVDC MVDC-anslutning; HVDC HVDC-punkt-till-punkt-länk; Modulär multilevelomvandlare; Transformatorstyrd MMC; Stabilitet DC felanalys;

   Abstract : För sammankoppling av multi-terminala HVDC-system med punkt-till-punkt kopplingar ärDC-DC-omvandlaren den enda möjliga sammankopplingen. Därför genomgår problemenmed spänningsmatchning och likspänningsströmbegränsning i högspännings DC-systemomfattande forskning samt ligger i fokus för denna avhandling. READ MORE

3. 22. Design and construction of a bidirectional DC/DC converter

   University essay from Uppsala universitet/Elektricitetslära

   Author : Alexander Wallberg; [2019]
   Keywords : Converter; DCDC; Energy storage; Single-phase; Omvandlare; DCDC; Energilager; Single-phase;

   Abstract : A four quadrant general single-phase bi-directional DC/DC converter was designed and constructed for high effect systems. The target application for the DC/DC converter was to be used to transfer energy between different energy storages, a miniature DC power grid and the high voltage AC power city grid. READ MORE

4. 23. Design and evaluation of a battery power supply for a mobile XRF measurement system

   University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

   Author : Xingyu Zhu; [2019]
   Keywords : XRF; Power; Battery; Boost-circuit; Buck-circuit; Voltage regulator;

   Abstract : X-ray fluorescence is a fast, non-destructive method to measure substances. This method can be used to detect elements in an environmental sample for elemental analysis. Commercially available XRF units exists, but their scope of application is limited. In the university lab, a more generalized XRF setup is available. READ MORE

5. 24. An FPGA Based MPPT and Monitoring System : suitable for a photovoltaic based microgrid

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Author : Rongpeng Zheng; [2019]
   Keywords : Microgrids; Monitoring System; Maximum Power Point Tracking MPPT ; Stand-alone Mode; Grid-connected Mode; FPGA; Verilog HDL.;

   Abstract : Microgrids containing photovoltaic (PV) cells and wind power gain more and more interest. These microgrids may work in stand-alone mode ("islanding") or be conncted to the main grid. In both modes of operation, power quality must be monitored and controlled. This report focuses on microgrids and aims to implement a monitoring system based on FPGA. READ MORE

6. 25. Design of Bidirectional DC/DC Battery Management System for Electrical Yacht

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Daniel Celius Zacharek; Filip Sundqvist; [2018]
   Keywords : Power electronics; bidirectional DC DC; converter; battery management system; renewable energy;

   Abstract : Electrical vehicles are getting more popular as the technology around batteries and electrical motors are catching up to the more common combustion engines. Electrical boats are no exception but there are still a lot of boats using old combustion engines that have a big impact on the environment. READ MORE
