Abstract
Efficient two-stage power factor correctors for three-phase diode rectifiers providing a power factor PF⩾0.995 are proposed, analysed and verified. The technique proposed is based on ripple-power conversion 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 power converter for optimum re-rectification of the ripple power
