| Abstract: | This paper presents a novel three-phase AC sampling technique which is based on the strong data processing capability of TMS320F2812 and the high speed multi-channel A/D converter AD7656. A reasonable accuracy is obtained by using a 12-point FFT algorithm The software and hardware of the system are outlined. |
