1. 1. A Differential Measurement Probe with High Common Mode Rejection

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Björn Franzén; [2018]
   Keywords : Common mode rejection; Fiber-optic measurement probe; Current Sensing; High voltage measurements; Optical isolation; Technology and Engineering;

   Abstract : Measuring signals with high frequency common mode components are typically prone to measurement errors due to low common mode rejection at high frequencies. The purpose of this master thesis is to design a measurement probe that presents sufficient common mode rejection to measure current on high voltage motor drives directly at the switching stage, before filtering.

3. 2. 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
