1. 16. DC-DC capacitor precharger

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Hannes Bydén; Alexander Lundström; [2020]
   Nyckelord :capacitor charger flyback converter; Technology and Engineering;

   Sammanfattning : This study evaluates the possibility of charging large capacitors to high voltages within short time frames. The system is designed to charge a capacitor of 4 mF from 0 to 850 V in one second by connecting a 24 V lead acid car battery to a flyback converter. LÄS MER

3. 17. Design of a planar transformer for a series loaded resonant converter

   M1-uppsats, Uppsala universitet/Elektricitetslära

   Författare :Andreas Bodegård; [2020]
   Nyckelord :planar transformer; design; PCB; Altium; series loaded resonant converter; SLRC;

   Sammanfattning : This report presents a project that has been made to present the design of a planar transformer as a part of a series loaded resonant DC/DC converter in a power unit. The design is based on an existing transformer that is not planar and so the characteristics of the transformer is translated into a planar version. LÄS MER

4. 18. MOSFET Packaging for Low Voltage DC/DC Converter : Comparing embedded PCB packaging to newly developed packaging

   Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Emil Dahl; [2020]
   Nyckelord :embedded components; embedded MOSFETs; MOSFET packaging; power module;

   Sammanfattning : This thesis studies the options of using PCB embedding bare die power MOSFET and new packaging of MOSFET to increase the power density in a PCB. This is to decrease the winding losses in an isolated DC/DC converter which, according to "Flex Power Modules", can be done by improving the interleaving between the layers of the transformer and/or decreasing the AC loop.

5. 19. Analysis Of A Wave Power System With Passive And Active Rectification

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Ferdus Wahid; [2020]
   Nyckelord :WEC; Optimal damping coefficient; Power smoothing; Passive rectifier; Active rectifier; Buck converter; Bi-directional DC-DC converter; Flywheel; Battery; Bi-directional voltage source converter; Voltage source inverter;

   Sammanfattning : Wave energy converter (WEC) harnesses energy from the ocean to produce electrical power. The electrical power produced by the WEC is fluctuating and is not maximized as well, due to the varying ocean conditions. As a consequence, without any intermediate power conversion stage, the output power from the WEC can not be fed into the grid. LÄS MER

7. 20. Modelling & Design of a Prototype DC/DC Converter for Trip Coil Applications

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Georgios Apostolou; [2020]
   Nyckelord :;

   Sammanfattning : High voltage circuit breaker testing is a major part in substation test industry. The minimum trip voltage test is one of the standard circuit breaker tests performed. LÄS MER
