Optimization of a series resonant DCIDC converter for traction applications
2012 IEEE Energy Conversion Congress and Exposition (ECCE), 2012To reduce weight and increase the efficiency in traction applications several power electronics based solutions have been proposed. Amongst them is the so called medium frequency topology (or power electronic transformer). However, up till now there has been no high power implementation of this topology that operates at switching frequencies that ...
