11. Efficiency of building related pump and fan operation - Application and system solutions
Abstract : The electric energy use in Swedish non-industrial buildings is 71 TWh per year out of which 30 TWh per year is used for the operation of technical systems. A significant part of those 30 TWh/year is used for pump and fan operation. The Swedish parliament decided in 2009 on a national energy and climate plan. READ MORE

15. Energy Efficiency Comparison Between Two-level and Multilevel Inverters for Electric Vehicle Applications
Abstract : In order to contribute to the development of energy and cost efficient electric vehicles, a thorough analysis of two different electric converter topologies is performed, considering different drive cycles and different control strategies. In the electric vehicles available on the market today, a high voltage (200−400 V ) battery pack composed of several battery modules is connected to one or more inverters which create AC voltages to the electric propulsion machines.
