Four Switch BLDC Motor Drive

Geethu James, Prof. K Radhakrishnan, Mrs.Jaya B

This paper describes the analysis and design of a low cost three phase inverter brushless dc motor (BLDC) drive. For effective utilization of the developed system, a novel direct current controlled pwm scheme (DPC) is designed and implemented.. The operational principle of the four-switch BLDC motor drive and the developed control scheme are theoretically analyzed and the performance is demonstrated by simulation.
