Power Factor Improvement in a Three Phase Circuit by using Vienna Rectifier and Buck-Boost Converter

Power factor is the ratio of true power or watts to apparent power or volt amps. The rapid placement of power electronic system in residential, commercial and industrial sides has energized the longing of an improved power factor to reduce the loss and cost. Good power factor deducts the losses and costs and ensure the longevity of electrical mechanism at a greater extent. Continuous researches are taking places everywhere. Several ways are invented to regulate it. As a part of those continuous researches, we worked under the challenge of the achieving the acme point in PFI segment. We utilized Vienna Rectifier and Buck-Boost Converter to design a PFI circuit. And at last, our design helped the power factor for being high as far as possible practically.
