The widely used resistance emulation technique for eliminating the problem of harmonic pollution of the power distribution system is based on the concept that the rectifier presents a pure resistive load to the ac system. In such a case, input voltage and current will have the same waveshape and will be in phase. Over the recent past, many methodologies based on the resistance emulation technique have been proposed in the literature. There has been a consistent attempt to introduce simplified control, higher efficiency and cost effectiveness in various emerging techniques. Scalar control method based resistance emulation technique, which is being discussed in this paper, is also an endeavor in the same direction. In this paper, the details of scalar control theory, analysis, modeling, simulation and experimental results obtained by using this technique have been presented.
