11. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

15. Fault diagnosis of a variable pole-phase motor
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Wound Independently Controlled Stator Coil (WICSC) machines are a novel type of multiphase machine with the ability to change its pole-phase configuration during operation. This enables improved post-fault control and thus prolonged continuous operation. READ MORE
