  1. 1. A Novel Two-Level Inverter Design for Efficient Energy Conversion in a Maglev Train Rail

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Oskar Zetterström; Stefan West Westholm; [2023]
    Nyckelord :IGBT; Inverter; Gate-driver; Prototype; Pulse width modulation; Sine wave; Maglev train; IGBT; Växelriktare; Grinddrivenhet; Prototyp; Pulsbreddsmodulering; Sinusvåg; Maglevtåg;

    Sammanfattning : This report covers the construction of a prototype inverter system designed to power the rail of a maglev train, from component selection through simulations and power demands to mounting and wiring the components into a cabinet. The inverter is made with insulated gate bipolar transistors controlled with pulse-width modulated signals provided by a custom microcontroller. LÄS MER

  3. 2. Estimation of Stability Margins for the Closed-Loop Air Charge Control of an Internal Combustion Engine Using Sinusoidal Disturbances

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Victor Sundelin; Filip Jussila; [2021]
    Nyckelord :Estimation; Stability Margins; Closed-Loop; Air Charge Control; Internal Combustion Engine; ICE; Sinusoidal Disturbances;

    Sammanfattning : The vehicle industry have for many years improved the design of car motors and iterated the control systems associated with it. The systems have become very complex and hard to understand because of this work process. LÄS MER

  4. 3. Vehicle dynamic simulation and powertrain simulation of a heavy hybrid vehicle with interconnected suspensions

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Florian Cellière; [2014]
    Nyckelord :hybrid vehicle; off-highway; low pressure tires; obstacle crossing;

    Sammanfattning : This thesis presents two simulations of a heavy hybrid vehicle, the first part of the thesis is focused on the specifications of the vehicle designed in accordance with the requirements based on the literature study of the soils where the vehicle will travel. The second part presents the study of the vehicle through two simulations. LÄS MER

  5. 4. Built-in self-test of analog-to-digital converters in FPGAs

    Master-uppsats, Linköpings universitet/Elektroniksystem

    Författare :Petter Nilsson; [2014]
    Nyckelord :FPGA; BIST; ADC; dynamic test; static test; linearity; DNL; INL; offset; gain error; FFT; SNR; THD; delta-sigma; sigma-delta; DAC; high-level synthesis; HLS; IEEE Standard 1241;

    Sammanfattning : When designing an ADC it is desirable to test its performance at two different points in the development process. The first is characterization and verification testing when a chip containing the ADC has been taped-out for the first time, and the second is production testing when the chip is manufactured in large scale.

  7. 5. Implementation of a Function Generator

    Kandidat-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Xin You; Yongchun Wang; [2012]
    Nyckelord :wave generator; sine-wave; square-wave; triangle-wave;

    Sammanfattning : Function generator has been widely used in each electronics fields recent years. In this thesis, the authors will introduce some basic structure and working principles of a function generator, moreover a function generator which can create three kinds of wave: sine wave, square wave and triangle wave has been implemented.
