ade7754 application note
Hi Everybody,
I have written a short topic on using ade7754. Please let me know wheather i'am on the right track. The aim of my discussion is to measure peak values of voltages.
The MMODE register defines the phase input on which the period measurement and peak detection are made. So if i keep that as constant say for R phase. Then in waveform register the Y and B phases will not come. Hence the display will be
|--------------------------------------------------------------------------------
|RPeak YPeak BPeak |
| |
| 230 0 0 |
If i have to get Y and B phases also then i will have to change MMODE register periodically. But the waveform register will always contain R phase so the Y and Bphase will be "0" always.
The So we haveto change WAVFORM refister(this register defines the speed and the analog input used for waveform sampling). So if we change this periodically then the waveform register will contain all the phases.Thus we can get the appropriate output.
|--------------------------------------------------------------------------------
|RPeak YPeak BPeak |
| |
| 230 230 230 |
FOr getting the peak we must read Vpeak and Ipeak registers. Can anybody worked on ade7754 help me with good application notes.I checked out analog.com but i did not get it, maybe because ade7754 is a new chip.:?::?:
