  1. 6. DC Motor driver for low RPM

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Stefan Ketelaars; [2016]
    Keywords : DC motor driver; DCDC converter; Pulse generator; H-Bridge; Back EMF.;

    Abstract : 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. READ MORE

  3. 7. Designing a brushed DC motor controller : Laying the framework for a lab experiment involving position control with current feedback

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Björn Franzén; [2015]
    Keywords : DC motor control; DC motor; DC motor position control; h-bridge; synchronous buck converter; torque feedback; current feedback; switched DC motor controller;

    Abstract : 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. READ MORE

  4. 8. Active rectification and control of magnetization currents in synchronous generators with rotating exciters : Implementation of the SVPWM algorithm using MOSFET technology

    University essay from Uppsala universitet/Elektricitetslära

    Author : Tomas Johansson; [2015]
    Keywords : rectification; SVPWM; space vector pulse width modulation; current control; active rectification; three phase;

    Abstract : 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.

  5. 9. Implementation of PID control using Arduino microcontrollers for glucose measurements and micro incubator applications

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Hugo Andersson; Viktor Mattsson; Aleksandar Senek; [2015]
    Keywords : ;

    Abstract : 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. READ MORE

  6. 10. Development of a Temperature Controlled Cell for Surface Enhanced Raman Spectroscopy for in situ Detection of Gases

    University essay from Umeå universitet/Institutionen för fysik
