11. Optimization of the Electric Properties of Thermoelectric Generators
University essay from Lunds universitet/Institutionen för reglerteknikAbstract : The efficiency in an internal combustion engine ranges from 25% to 45%. About 50% - 85% of the overall energy losses in a combustion engine is heat which is either cooled away by the vehicle's radiator or blown out with the exhaust gases. READ MORE

12. AC Ion Current Interface
University essay from Institutionen för ingenjörsvetenskap, fysik och matematikAbstract : An effective way to extract combustion parameters from a spark ignited engine is to measure the level of ionization. One way to do this is to use the spark plug as a sensor. Until now this has been achieved by applying a DC voltage over the spark gap which causes an electrical field. READ MORE

13. Dimensionering av reservkraftsaggregat för kopplings- och transformatorstationer
University essay from KTH/Elektriska energisystemAbstract : Questions raised on the basis of this work are, witch loads are there at the stations, how big are the loads, are there nonlinear loads, are there motor loads with high starting currents, how do the rectifiers interact with batteries? The diesel unit starts about 10 minutes after a regional or national interference in a transformer station. The station’s DC power system is then fed during that time from batteries. READ MORE

14. Nonlinear Modeling of Locomotive Propulsion System and Control
University essay from Lunds universitet/Institutionen för reglerteknikAbstract : In this report the motor side of a converter driven AC-locomotive is studied and modeled. The motor side consists of an asynchronous electrical engine, an indirect self controller, a voltage converter, a Pulse Width Modulator(PWM) and the train mechanics. The converter is supplied with voltage from a DC-link. READ MORE
