A literature survey on AC-DC Converter using three phase single stage PFC & PWM Technique

Abstract

Today to achieve ac-dc power conversions with high input power factor and low harmonic distortions, Power factor correction (PFC) converters are widely used. This paper lays out the research and development done in the field of PFC’s. Converter topologies, control strategies, power quality etc has been discussed here. Higher power ratings, faster switching speed and lower cost are the areas of concern for digital controllers and converters and thus PFC has gained attention.
