ANALYSIS AND CONTROL OF FOUR QUADRANT OPERATION OF THREE PHASE BRUSHLESS DC (BLDC) MOTOR DRIVE

This paper gives a control for three phase brushless DC (BLDC) motor in all four quadrant operation. The control system in this paper is capable to detect and identify the rotor position by sensor signal [1]. In this paper behaviour of BLDC motor is studied in all four quadrant operations through simulation model. The simulation is carried out for four quadrant operation and during regenerative braking kinetic energy is wasted as heat energy. This paper gives utilization of wasted kinetic energy is converted and stored in battery. The simulation model shows the control for four quadrant operation [2]. From this paper during regenerative braking instead of wasting kinetic energy can be considerable as saving of power
