Abstract

Recently, due to significant increase in demands of electric motors, design and manufacturing of high efficiency motors and related variable speed drives have been regarded by many suppliers. Among several kinds of motors, the brushless DC (BLDC) motor has many advantages including high torque capability. In this paper, for the first time, the possibilities of direct power control (DPC) of BLDC motors fed by a voltage source inverter have been studied. Principles of this method have been separately evaluated. The BLDC motor has been driven with three control method. The results show that the DPC technique enjoys all advantages of pervious method such as fast dynamic and ease of implementation, without having the previous method problems. The Simulations were carried out for the closed-loop speed control systems under various load conditions to verify the proposed methods. A modified DPC method with 12 sectors is presented to improve the performance of the direct power control method for BLDC motor drive. Theoretical analysis and performance of the developed controller is confirmed via simulation at different speed and under various disturbances.   Keywords: Direct power control (DPC), brushless DC motor (BLDCM), hysteresis control, automotive, drive
