An Efficient Method of Controlling AC Power Using DSP 2407-A Controller


S.A. Hari Prasad, R.Nagaraj


Vol. 8  No. 9  pp. 297-300


This paper presents the design and hardware implementation of ac power controller card using TMX320LF DSP 2407A controller. Sinusoidal PWM technique is used to control the ac power. The on chip capture unit is made use of to sense the speed of the AC motor which reduces the hardware. The designed controller is tested by regulating speed of an AC motor in closed loop and the results show comprehensive efficiency in terms of set speed to speed achieved.
