DC drives are still very important especially for low voltages and low power (e.g. in cars and robots). In this paper a Cuk-derived (one- and two-quadrant) converter is analyzed which makes it possible to control the voltage across the machine (and therefore the speed) from zero to three times of the input voltage. The model of the drive, the design of the devices, and some experimental results are...
This paper deals with an effective drive control scheme for separately excited DC motors. Distinctive feature of the work is the modelling of the motor as a two-input single-output non linear system that allows the armature voltage to be maintained to the maximum full output voltage of the converter during flux weakening operation while the armature current is controlled by the excitation one. Experimental...
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...
