Gw. Moon et al., MAGNETIC-COUPLED HIGH-POWER FACTOR CONVERTER WITH LOW LINE CURRENT HARMONIC DISTORTIONS FOR POWER-FACTOR CORRECTION AND FAST OUTPUT RESPONSE, IEEE transactions on industrial electronics, 45(4), 1998, pp. 552-558
A new magnetic-coupled high power factor converter (MCHPFC) with a sin
gle switch/single stage is proposed. The proposed converter gives good
power factor correction, low current harmonic distortions, and tight
output voltage regulation. The prototype shows that the IEC555-2 requi
rements are met satisfactorily with nearly unity power factor. A propo
sed MCHPFC is particularly suited for low-power-level power supply app
lications.
