Description
Summary:Permanent Magnet Brushless DC (PMBLDC) machines are more popular due its simple structure and low cost. Improvements in permanent magnetic materials and power electronic devices have resulted in reliable, cost effective PMBLDC drives, for many applications. Modelling, simulation and experimentation of drives with new converter configuration and control schemes are essential for making this drive competitive. In this paper, State Space modelling of BLDC motor are described and using these model simulated BLDC Drive System in both Matlab/Simulink and LabView. The Fours-witch voltage source inverter topology is used to reduce the switching losses. The torque ripples reduction is discussed with hysteresis current controller. Hardware implementation is done with DSP processor TMS 320LF2407.
