Certain CCFL driver topologies produce an asymmetrical output voltage which causes migration of the mercury to one side of the CCFL tube. It is known that a DC voltage component across the CCFL leads to this effect. However, even when no DC component is present across the lamp, migration takes place if the voltage is asymmetrical. Eventually, in the absence of a series ballast capacitor, a DC current...
A hybrid electric Kart is built as a didactical project for the students of the Master of Engineering: Energy of the K.U.Leuven. In order to cope with the growing number of students, a modular hybrid electric kart is conceived. The hybrid configuration allows to diversify between several tasks that have to be addressed by the students. The tasks include a control scheme for an induction motor, a control...
