Original Abstract

This contribution describes a possibility to use an ultracapacitor in order to increase the efficiency of an electric drive with a traction accumulator. A 2-quadrant converter is used to connect the ultracapacitor into the DC link of the traction inverter (the accumulator). The elimination of heavy current peaks with both polarities is guaranteed by an appropriate control algorithm. This current peaks are caused by the main traction inverter during an acceleration from non zero starting speed or regenerative braking. An attention is paid to the energy and voltage relations. A suitable control structure is introduced.
