Abstract: |
The application of embedded PC technology in power fault recurrence device is introduced. The embedded PC is used to realize man-machine interaction and send demands to digital signal processor module through serial ports,for producing pulse width modulation waves to control power amplification output. The closed - loop technology is applied to modify the original data with the feedback sampling data,minimizing the non-linear distortion and ensuring little distortion of power fault recurrence waves. |
