  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. An amplitude modulated laser rangefinder : electronic circuit design and implementation

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och system

    Författare :Fazel Naser; Stefan Morin; [2022]
    Nyckelord :Amplitude modulation; Phase shift; Laser rangefinder; Drive electronics; PCB; Colpitts crystal oscillator; Transimpedance amplifier;

    Sammanfattning : This report describes the design and implementation of a prototype for an amplitude modulated laser rangefinder, which is made on a PCB consisting of a laser module emitting light, a photodiode receiving the light reflected from the target, and other components. The design is made for the different power levels, generation of the modulation output and the reception of the signal. LÄS MER

  4. 3. 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

  5. 4. A self-calibrating system for finger tracking using sound waves

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Linus Hammarlund; [2017]
    Nyckelord :cfrc; gcc-phat; srp-phat; self-calibration; toda; toa; Technology and Engineering; Mathematics and Statistics;

    Sammanfattning : In this thesis a system for tracking the fingers of a user using sound waves is developed. The proposed solution is to attach a small speaker to each finger and then have a number of microphones placed ad hoc around a computer monitor listening to the speakers. LÄS MER

  7. 5. Investigation of active anti-roll bars and development of control algorithm

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Harshit Agrawal; Jacob Gustafsson; [2017]
    Nyckelord :Active anti-roll bar; suspension; chassis; vehicle dynamics; handling; ride comfort; roll; yaw; PI-controller; sliding mode controller.;

    Sammanfattning : Active anti-roll bars have recently found greater acceptance among premium car manufacturers and optimal application of this technology has emerged as an important field of research. This thesis investigates the potential of implementing active anti-roll bars in a passenger vehicle with the purpose of increasing customer value. LÄS MER
