| Abstract |
Delta-Sigma modulation is currently used as an intermediate stage in ND and
DJ A conversion, and recently it has also been adopted in signal processing to perform arythmetic operations. Some types of Power Factor Correction circuits, introduced· in the electric power area to sinusoidally shape the AC line current and to place it in phase with the line voltage, contain in the control stage a multiplier block which could be advantageously realized with the Delta-Sigma technique. This work describes the implementation of such a multiplier block and reports the preliminary experimental results
carried out on a laboratory prototype of the complete PFC system. |
