| Abstract |
Efficient two-stage power factor correctors for three-phase diode rectifiers to ensure a close-to-unity
power factor are proposed, analyzed, and verified. The technique proposed is based on the ripplepower
re-rectification into an additional quantity of the DC output power. The new schemes contain a
series-resonant third-harmonic filter and a low-power auxiliary AC-DC converter for optimum ripplepower
re-rectification. An advantage of the new schemes is elimination of the magnetic thirdharmonic
current injection device used in the previous schemes. The high values of the power factor
hold in the wide range of the load and supply-voltage variation. |
