2. Power Flow Analysis of the Swedish Railway Electrical System
Abstract : This thesis deals with analysis of the steady state power flow in the Swedish railway electrical system. Finding the steady state of the system means that all voltages and power flows in the system are known. The trains are supplied from the public grid using frequency converters. READ MORE

4. Power Control Systems for PM Synchronous Flywheel Alternators
Abstract : Flywheel systems are attractive in hybrid and electric vehicles, being able to handle the large power when accelerating and for regenerative braking. The combination of a flywheel device with a battery source has several advantages, such as higher peak power capacity, higher energy density and a decrease of the number of charging/discharging cycles in the battery.
