Digital Energy Meter..Help Needed


Joined Apr 20, 2004
If this is homework, then you get the most benefit from doing the figuring out. The data sheet has a reasonable good explanation of the voltage and current converter circuits. Have you tried to relate the data sheet circuit explanation to the schematic?

Google is good for supporting material about current transformers and so on. The circuits are being used to produce analog representations of the voltage and current waveforms that the uC can handle (and assign engineering units to without a lengthy calibration procedure).

If you have problems with op amps and gains, our Ebook has good material about that.

Well this is a project i have to do...I read the data sheet but i didn't understand exactly how does this work

I mean what each circuit do and so on..if you could explain it for me i would be grateful :)
