1. 1. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
   Keywords : high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

   Abstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

3. 2. Design and Simulation of a 10kW High-Efficiency Dual Active Bridge Converter

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

   Author : Fan Yang; [2023]
   Keywords : Converter Design; Dual Active Bridge; Single Phase Shift Modulation; Extended Phase Shift Modulation; Efficiency Estimation; Konverterdesign; Dual Active Bridge; Single Fas Shift Modulation; Extended Phase Shift Modulation; Effektivitetsuppskattning;

   Abstract : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. READ MORE

4. 3. Magnetic and Dielectric Design of Auxiliary Power Supply for HVDC Applications : A high-frequency transformer with high power transfer capability and high voltage electrical insulation

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

   Author : Henrik Johansson; [2022]
   Keywords : Auxiliary Power Supply; HVDC; Inductive Power Supply; High Voltage Insulation; High-Frequency Transformer; Hjälpkraftsförsörjning; HVDC; Induktiv Kraftförsörjning; Högspänningsisolation; Högfrekvenstransformator;

   Abstract : It is anticipated that massive amounts of energy will be transferred long distances via High-Voltage Direct Current (HVDC) links in the future and the prospect of having meshed HVDC grids is envisioned, for example the European super grid. Such a power system would benefit greatly if HVDC circuit breakers could reliably clear faults within the HVDC network. READ MORE

5. 4. Design of a planar transformer for a series loaded resonant converter

   University essay from Uppsala universitet/Elektricitetslära

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

   Abstract : 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. READ MORE

6. 5. 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.
