The Development Trend

Correction Technology on active power factor is now widely used in AC-DC power supply circuit to eliminate harmonic of power system, to improve the power factor. Firstly the method of power factor correction technology is set out. Secondly, the basic principle of active power factor correction technology is analyzed, then the control method for active power factor correction technology is given. Finally the development trend of active power factor correction technology is analyzed.

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.
