A Review on Quadratic Boost Topology-Based PFC Techniques

Electronic devices require DC voltage for their operation so rectification (AC to DC conversion) is needed to convert AC voltage from the mains to DC. During this conversion, harmonics are generated in the system as well as power factor (PF) gets poor hence degrading power quality. Power factor correction (PFC) converters are being commonly used to increase PF and reduce harmonics. Boost PFC Converter is the mostly used topology for active power factor correction because of several benefits like series input inductor, high PF, but its voltage gain is not that good and it has output voltage ripple. Quadratic Boost PFC Converter can be used to overcome these two drawbacks by providing high voltage gain and less outputvoltage ripples. This paper represents applications and topologies of Quadratic Boost Converter, latest control techniques to achieve high voltage gain, regulated output and, high PF. Also, comparison is made between Boost Converter and Quadratic Boost PFC Converter. Finally, conclusion is made of this survey
