Several typical circuits of AC voltage and current conditioning and filter circuit were summarized according to the different situations of electric energy measurement. The circuits of signal rising standard values were given in the paper, these circuits were compared, analyzed and evaluated. An AC voltage and current signal conversion circuit was designed which could detect the 50 times harmonic component of 50Hz AC power.
