A Universal Bldc Motor Drive With Optimized Performance

In this paper, an enhanced input converter circuit for Brushless DC motor drive system is presented. Drive’s converter circuit is designed in such a way to realize all the standards of input power system. Based on the signals frominput voltage divider, converter generates a constant DC bus voltage to drive the Brushless DC motor. Drive's inverter designed with SPWM instead of square PWM, hence there is no pulsation torque. The experimental results are presented to verify the stability of the driver system. Various torque and RPM have been plotted during low voltage 110V and high voltage 230V.
