Abstract :
Delta modulation offers a number of unique advantages in static PWM inverter applications in variable speed AC drives. The performance of a delta modulator is investigated in this paper for a square wave reference signal. This changeover from sine wave reference signal to square wave reference signal can reduce the cost of the control circuit significantly which is crucial in FHP drive range. The parametric sensitivity of this modulator is studied in this paper
