6. DC Motor driver for low RPM
Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Sammanfattning : For this project the main goal was to design, simulate, build and test a DC motor driver. To accomplish this four specific parts had to be design. First a DCDC converter that converts the input signal from an external power supply in a controllable DC output. LÄS MER
7. Designing a brushed DC motor controller : Laying the framework for a lab experiment involving position control with current feedback
Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Sammanfattning : In order to provide the means to set up a control theory lab experiment involving position control of a brushed DC motor with current feedback, a pulse-width modulated motor controller was designed. The output voltage is controlled by an analog reference signal and the magnitude of the output current and voltage are measured and output. LÄS MER
8. Active rectification and control of magnetization currents in synchronous generators with rotating exciters : Implementation of the SVPWM algorithm using MOSFET technology
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : This thesis aims to design and build a power electronics system for the rectification and control of magnetization currents in synchronous generators with rotating exciters.The rotating exciter provides three-phase AC while the generator rotor needs DC with a high degree of control.

9. Implementation of PID control using Arduino microcontrollers for glucose measurements and micro incubator applications
Kandidat-uppsats, Uppsala universitet/Fasta tillståndets elektronikSammanfattning : The task is to build a low-cost thermostat and design necessary elements to perform a study on water mixed glucose-impedance at different temperatures and cell growth in a temperature-controlled incubator housing a magnetic field of up to 3 mT. The incubator was designed in solidworks and made to fit petri dishes of two relevant sizes and necessary wiring. LÄS MER
10. Justerbar modell av transmissionsledning för elkraftsöverföring
Uppsats för yrkesexamina på grundnivå, KTH/Data- och elektroteknikSammanfattning : Detta examensarbete har utförts på uppdrag av Terco. Tercos PST 2220Transmission Line and Distribution Module fungerar som en fysisk modellav ett verkligt transmissions- eller distributionsnät där fem olika typer av nätmed avseende på längd, spänningsnivå och skenbar effekt är möjliga.
