Comparison of brushless DC motor drive performance fed by two different front end DC – DC Power converters [articol]

Abstract

The importance of Brushless DC motors has been increasing across domestic and industrial applications for a multitude of advantages. This paper concerns the implementation of the brushless DC motor with two different front end DC–DC converter topologies, canonical switching cell (CSC) converter and Landsman converter. The performance of the motor in these topologies are compared. MATLAB/Simulink is used to design and simulate the converter circuits. The motor parameters under discussion are stator back emf, rotor speed and its ripple factor. A conscious effort has been made to present the parameter values in an easily comparable and a conclusion has been drawn on the best possible topology among these two to enable the motor to function efficiently and help us get desirable results when the motor is deployed in operation.
