1. 1. Investigation of electromagnetic compatibility (EMC) of low-voltage (<60V) DC electric motors in construction machinery application

   University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

   Author : David Luong; Ibrahim Salloum; [2019]
   Keywords : EMC; brushed dc motor; arcing; inrush currents; X2Y capacitor; NTC thermistor; common mode ferrites; differential mode ferrites; grounding; cable placement; motor design parameters;

   Abstract : The brushed DC motor is a source of electromagnetic emission that may cause interference. The main issues with brushed DC motor are arcing, which occurs between the brushes and commutator, and inrush current. It is possible to decrease the electromagnetic emissions by addressing the source (brushed dc motor) and the installation. READ MORE

3. 2. On-line estimation of junction temperatures in power modules

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Josefin Lund; [2014]
   Keywords : junction temperature estimation; foster circuit; thermal Ohms law; thermal resistance; thermal capacitance; time constant; Technology and Engineering;

   Abstract : It is critical for the durability of power modules to maintain low enough temperature in their components (IGBTs and diodes). The goal of this project was to examine methods to estimate the junction temperature of components in an IGBT module in real-time. READ MORE
