A novel switching mode power supply (SMPS) with input/output isolation is presented, which compounds the three-phase power factor corrector (PFC) with a full bridge converter in a single-stage. It solves the problem of over-voltage on the DC link due to pseudo-phase-shifting control (PPSC) mode. Its operating principle and critical parameters are analyzed. Experiment results of an isolated 10 Kw prototype show that the power factor of the system is above 0.99 and the soft-switching mode reduces most of the EMI.

The fundamentals of power factor correction The fundamental issues of power factor analysis for non-sinusoidal waveforms are described. A full-wave rectifier circuit is analysed and original approximations are derived for voltage ripple, peak diode current and input power factor. A power factor correction technique, based on a switching mode power supply, is presented.

This paper presents a new single-stage single-switched forward converter with magnetic coupled nondissipative snubber, which gives good power factor correction (PFC), low current harmonic distortion, and tight output voltage regulation. The proposed converter features low switch current and voltage stresses, essential for the design of a single-stage power factor correction converter. The prototype shows that the IEC1000-3-2 requirements are met satisfactorily with nearly unity power factor. This proposed converter with magnetic coupled nondissipative snubber is particularly suited for power supply applications with low power level.
