Abstract |
|
Brushless DC (BLDC) motor drives are becoming more popular in industrial and traction applications. Hence the control of BLDC motor in four quadrants is very vital. The flexibility of the drive system is increased using digital controller. In this paper the PWM signals for driving the power inverter bridge for BLDC motor have been successfully implemented using a dsPIC controller and the motor can be controlled in all the four quadrants without any loss of power .Energy is conserved during regenerative braking period. The digital controller dsPIC, is advantageous over other controller, as it combines the calculation capability of digital signal processor and controlling capability of PIC microcontroller to achieve a precise control. Simulation of the proposed model is done by using MATLAB/Simulink. |
