AC-DC Converter with Flying Capacitor Using Three Phase Single Stage PFC & PWM
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
Today the wide usage of non linear loads like variable speed drives has made power factor improvement difficult due to the presence of harmonic currents. These harmonics cause overheating, and the amplification of these harmonics cause failure or damage of Capacitors and other system components. Thus this paper presents a new integrated AC-DC converter with single stage power factor correction with flying Capacitor. Due to the interleaved structure, the proposed converter operates at lower input ripple current and has improved load efficiency along with peak switch currents and soft switch operation. The convertor has improved efficiency and due to single stage 3 level AC-DC converter it has voltage regulation along with power factor correction. This proposed converter is stimulated in the MATLAB software and the design and performance is further studied and analyzed.
