"Many times, the designer wishes to generate a DC signal from an AC current transformer for input to a PLC or data acquisition system, or even as part of a current or motor controller. Creating DC from an AC source creates problems with diode voltage drops and the variances over temperature and current. The following circuit provides an accurate method for creating this DC signal."
CRMagnetics provide very good reference material about current transformer (CT) on the web, with clear illustration of circuits and some computation methods.
Free software for unit converter as isslustrated in the above graph.
