Abstract
This paper displays another power converter topology to stifle the torque swell because of the stage current replacement of a brushless dc engine (BLDCM) drive framework. A combination of a two level inverter (2-level inverter), a Super lift positive luo converter (SPLC), Fuzzy logic controller and a dc-bus voltage selector circuit is employed in the proposed torque ripple suppression circuit. For efficient suppression of torque pulsation, the dc-bus voltage selector circuit is used to apply the regulated dc-bus voltage from the positive super lift luo converter during the commutation interval. In order to further mitigate the torque ripple pulsation, the two level inverter is used in the proposed circuit. Finally, simulation results show that the proposed topology is an attractive option to reduce the commutation torque ripple significantly at low- and high-speed applications.
