1. 6. Simulation of a Battery Energy Storage System for Fast Frequency Reserve Support.

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Pathirage Dona Upekha Nimanthi Pathirage; [2022]
   Nyckelord :Energy Storage; Renewable Energy; Battery; Fast Frequency Reserve; Lithium-ion;

   Sammanfattning : Electricity providers has a growing interest in moving towards Renewable Energy Sources (RES) for power generation due to their attractive features. This has caused phasing out of coal, oil and nuclear power plants which use large synchronous generators for power production. LÄS MER

3. 7. Commissioning and Testing of a Novel Buck-Boost Phase-Modular Three-Phase AC/DC Converter with Low Component Number

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

   Författare :Saransh Chhawchharia; [2022]
   Nyckelord :;

   Sammanfattning : In this thesis, a 1kW hardware prototype of a three-phase inverting buck-boost converter, termed as 6 Switch Buck-Boost Y-Inverter (6YI) is commissioned and tested. The 6YI is designed to be used as a motor drive for renewable energy applications such as fuel cell, solar etc powered motor drives with wide input voltage capability. LÄS MER

4. 8. 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

5. 9. 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

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

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Abidemi Oluremilekun Eleyele; [2020]
   Nyckelord :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;

   Sammanfattning : 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.
