This paper presents the design and implementation of a three-phase high power factor mains interface concept appropriate for many power electronic applications such as supplies for dc power distribution systems in telecommunication, electric vehicle battery charging, future more electric aircraft, variable-speed ac drives, and high power lighting systems. The circuit topology comprises a buck-type power factor correction rectifier circuit built by the combination of an active third-harmonic injection rectifier and a series-connected dc-dc buck-type converter. The characteristics of this rectifier topology, including the principles of operation, modulation strategy, suitable control structure, and dimensioning equations, are described in this paper. The feasibility of the presented converter for buck-type rectifier applications is demonstrated by means of a constructed hardware prototype.
