Speed control of BLDC motor using sinusoidal PWM technique

Efficiency and Reliability are the key features for the development of advanced motor drives. Residential and commercial appliances such as refrigerators and air conditioning systems use conventional motor drive technology. A brushless DC (BLDC) motor drive is characterized by higher efficiency, lower maintenance, and higher cost. Therefore, it is necessary to have a low-cost but effective BLDC motor controller. PWM has been widely used in power converter control. PWM control is the most power full technique that offer a

simple method for controlling of analog system with processors digital output. PWM frequency depends on the target FPGA device speed and duty cycle resolution requirement. In this paper, BLDC motor drive controlled using FPGA controller.
