1. Design and construction of a reliable wireless power transfer system for an embedded device : With emphasis on industrial applications
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : This thesis deals with wireless power transfer from an external source to embedded small devices (such as for conditioning monitoring, control etc.) located at different distances from the source. The proposed designs can be used in a variety of applications, including mobile phones, electric cars, unmanned aerial vehicles, robots, etc. LÄS MER
2. Exploring electromagnetic induction as a power source for interactive human-powered devices
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In the last decade, we have seen an increasing interest in the designing of interactive technology that is limited in energy usage to our bodily capabilities. This field is commonly referred to as Human-Power Interaction (HPI). The aim of HPI is to create battery-free devices that are powered solely from human interactions. LÄS MER
3. Manufacturing Effects on Iron Losses in Electrical Machines
Master-uppsats, KTH/Elektrisk energiomvandlingSammanfattning : In this master thesis, the magnetic properties of SiFe laminations after cutting and welding are studied. The permeability and the iron loss density are investigated since they are critical characteristics for the performance of electrical machines. LÄS MER
4. Reducering av släpförluster
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : För att öka köreffektivitet och säkerhet samt minska bromsarnas slitage är de flesta av Scanias lastbilar och bussar utrustade med en hjälpbroms, så kallad retarder. En retarder arbetar generellt sett enligt någon av följande två principer. LÄS MER
5. Överföring av elektrisk signal och effekt med magnetisk induktion.
Uppsats för yrkesexamina på grundnivå, Institutionen för datavetenskap, fysik och matematik, DFMSammanfattning : This report tested the possibility of using induction as a mean for transferring data and power so that it can be implemented as a communication medium between a terminal and measuring head mounted in a measuring frame. This would eliminate the need for the cable bunches that are used today. LÄS MER
