Abstract

This paper presents a new three-level converter for three-phase power factor correction and output voltage regulation in a single stage of power conversion. The AC side of the proposed converter operates in DCM to obtain power factor correction. On the other hand, the DC side of the converter may operate either in CCM or DCM. The interest in operating the DC side in DCM is to limit the maximum intermediate bus voltage to realistic values. The paper presents the PWM and the phase-shift control versions of the proposed converter. All the power switches operate under a zero-voltage turn-on condition. The harmonic distortion generated by the proposed converter is lower than the distortion produced by the conventional three-phase single-switch DCM boost rectifier. Theoretical analysis, design guidelines, and experimental results are provided for a prototype rated at 3 kW and operated at 100 kHz
