1. Development of a High Current Charger for Small Electric Boat Commuting
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Electrification of the transport system is an important societal project which we are currentlyundergoing. With improvements in battery technology it is now possible to construct quite powerfulpersonal vehicles to replace combustion engines in not only cars but also motorcycles and boats. LÄS MER
2. DC-DC Converter for Fast Charging with Mobile BESS in a Weak Grid : Enabling remote charging and increased efficiency with less resource intensity
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : With the increase of electric vehicles (EVs) on the roads the availability of charging infrastructure becomes more important. Today it is relatively straightforward to install fast chargers in areas with strong power grid connections, such as in urban areas. LÄS MER
3. Life Cycle Assessment of Electric Road Systems - Climate impact in comparison with battery electric vehicles, biogas vehicles and fuel cell electric vehicles
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystemSammanfattning : One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where vehicles are charged dynamically.

4. Isolated Single-Stage Interleave Resonant PFC Rectifier with Active and Novel Passive Output Ripple Cancellation Circuit
Master-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : 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.

5. Making grid capacity available through heat pump control
Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaperSammanfattning : In this report the problem of constructing a bus depot with electrical buses despite the lack of grid capacity, was analyzed. A potential solution is investigated, namely smart control of heat pumps in industries. LÄS MER
