ac voltage divider
If we need to measure AC voltage of around 50V to 500V, do we sure need a precision rectifier

Hi Garg ,,,
Surely there is a need for u to provide a precision Rectifier . Because .. Any high voltage could be brought into the lower level with the normal Voltage Divider. But the Voltage divider Output cannot be measured as it is .. and it need to n\be rectified inorder to give it to an ADC .
In rectification process , the Output Voltage you could measure is the Peak Voltage . If the Voltage input provided to u is a Chopped or controlled AC , Then the Change in Voltage could not be identified by your hardware.
So the better is you go with precision Rectifier.
