Switched mode single-phase ac to dc converters are having positive aspects like high efficiency and power density. That paves the way for usage as common rectifiers for various applications ranging from home to industry. These converters of classical type, however, draws input ac currents which are non-sinusoidal which results into low input power factors and this causes invasion of harmonics directly to subject power lines. Harmonics have downgraded effect in the function of any electrical system and hence they need to be removed. Research conducted in the analysis of many similar techniques for input current wave modification has brought down and pointed all the drawbacks. Filters (passive) have the demerit of fixed compensation, bulky shape and resonance state. But, active filters improve the power quality of the input current and subsequently they improve the power factor. The Power Factor Correction (PFC) which is an active filter based method provides efficient means for reducing harmonics. Above circuits reduce harmonics and also they enhance power factor. This work enumerates a comparative study of two topologies (proposed) of single-phase ac-dc boost converters with enhanced power factor correction capability. Both the open and closed loop control modes are discussed for the considered two converter topologies. Simulation studies have been carried out using SIMULINK tool in MATLAB environment.
