摘要：AC/DC converters are widely used in industrial applications. Input AC voltage is rectified and filtered using filtering circuit which consists of large electrolytic capacitors. These capacitors draw a large amount of current and the efficiency of the converter system decreases drastically. Low power factor, high harmonic distortion and large ripple factor have made the converter system inefficient. This paper analyses about different converter topologies and proposes a different design by which power factor can be improved and harmonic distortion can be reduced. The results of respective topologies are shown through P-simulation program with integrated circuit emphasis (PSPICE) simulation and their parameters are calculated. Five parameters are considered for the comparison of these topologies.
