1. 1. Boost Converter Inductor Design for High-Power Fuel Cells Using Pareto Optimisation for Single and Coupled Cores

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

   Författare :Lucas Tunelid; [2022]
   Nyckelord :Fuel Cells; Interface Converters; Inductor Design; Mutiobjective Optimisation; Bränsleceller; Gränsnittsomvandlare; Induktor Design; Multiobektiv Optimering;

   Sammanfattning : Hydrogen has been identified by the European Commission to be a competitive alternative to fossil fuels within the transport sector in the medium to long perspective. Because of this, an increased understanding is required of the electrical power train present within such vehicles. LÄS MER

3. 2. Comparative Analysis of Several Designs of Modular Multilevel Converters with Interleaved Half-Bridge Submodules

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

   Författare :Lingyu Chen; [2022]
   Nyckelord :Modular multilevel converters MMC ; interleaved half-bridge submodule; interleaved converters; power loss calculation; converter efficiency; converter dimensions; Modulära multilevel-omvandlaren; interfolierad halvbrygga submodul; interfolierade omvandlare; effektförlustberäkning; omvandlareffektivitet; omvandlardimensioner;

   Sammanfattning : The Modular Multilevel Converter (MMC) is one of the most commonly used active converters in the high-/medium-voltage sector due to its many advantages such as high scalability, high efficiency, modularity and low harmonic contents. However, in low-voltage and high-current applications, classical MMC designs are not very economical. LÄS MER

4. 3. 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.

5. 4. Distortion Cancellation in Time Interleaved ADCs

   Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Naga Thejus Sambasivan Mruthyunjaya; [2015]
   Nyckelord :Time-Interleaved ADC; Post correction; Blind calibration; Harmonics cancellation; Mismatch analysis; Linearisation;

   Sammanfattning : Time-Interleaved Analog to Digital Converters (TI ADC) consist of several individual sub-converters operating at a lower sampling rate, working in parallel, and in a circular loop. Thereby, they are increasing the sampling rate without compromising on the resolution during conversion, at high sampling rates. LÄS MER

7. 5. Digital compensation of nonidealities in time-interleaved ADCs

   Uppsats för yrkesexamina på avancerad nivå, KTH/Signalbehandling

   Författare :Anders Haponen; [2014]
   Nyckelord :;

   Sammanfattning : Mismatches between the analog to digital converters (ADCs) in time-interleaved sampling causes spurious signals, limiting the performance of the architecture. This thesis introduces the most commonly modeled mismatches, analyses their e ects and reviews and evaluates state-of-the art compensation methods published in recent papers. LÄS MER
