I am working on a project that requires me to convert and AC voltage to a DC voltage. The AC voltage is from a CT that is then rectified to output DC. The DC is then read by a A/D converter (1.75VDC range). I know the rectifier circuit is not very clean and am not sure if a filter is the best answer. I am thinking about a True RMS-to-DC converter, but would like some feedback because the output from the CTs is variable. Can anyone help?
