Abstract

Brushless DC (BLDC) motor drives have gained much popularity and are widely used in industrial and traction application. They are more superior because of their high power to weight ratio, low maintenance, high-efficiency, high flux density per unit volume. They are generally preferred over brushed DC motors for several other applications. This proposed approach presents BLDC motor drive without sensors for low power applications. A PFC (Power Factor Corrected) BL (Bridgeless) buck-boost converter is operated in DICM (Discontinuous Inductor Current Mode) to supply a unity Power issue at AC mains. In case of sensorless motors the control of the motor will be achieved by monitoring the back EMF zero crossing as a feedback. The concept of BLDC motor is well simulated in MATLAB/Simulink atmosphere.
