Implementation of a Boost Converter for Power Factor Correction in Dual Mode

SEEE DIGIBOOK ON ENGINEERING & TECHNOLOGY, VOL. 01, MAY 2018 pp. (21-24)
Abstract– With the increased demand for electronic equipment in our day-to-day life, the line current harmonics of this equipment should be limited for meeting the regulatory standards and for the efficient working. This can be achieved by incorporating a simple power factor correction circuit. Power factor is a term representing the qualitative measure of the power quality in an electric system. A load with low power factor draws more current than a load with high power factor for the same amount of useful power transferred and this necessitates the need for power factor improvement. There are many techniques for power factor improvement. In this paper we deal with a boost converter, working in dual mode to implement power factor correction. The working of the converter in two different modes namely continuous conduction mode and critical conduction mode not only offers input power factor correction but also provides high efficiency in both light load and heavy load conditions. Since the converter will raise the output voltage, a single converter can be used instead of several batteries for the same amount of voltage thereby saving space. The model is simulated using MATLAB Simulink software.
