ad73360 arm

i want designed the three-phase power meter using arm and ad73360,somebody can give me help at dsp
 

Hi,



Instead of using ad73360, I would like to suggest you the usage of the ADE7753 (or its poly-phase counterpart).

This family of ICs has a built-in "dsp engine" that does all the "dsp computation related to energy/power measuring" for you. Once using it, the only thing to do is to read its registers of energy/power measurements, what can be done by means of a SPI interface.


Best regards.

It is not a problem because you can get the samples of the current and voltage waveforms that are used by the IC. You may use them to calculate the harmonics.

You may also use the CS5463 IC from CirrusLogic.

Best regards
