Abstract :
A new single stage power factor corrected AC/DC converter for universal input is proposed, which is unified with a buck topology. The DC link voltage of the proposed converter is always lower than the peak input voltage at any load condition. Using this distinction, the problem of high DC link voltage under light load conditions of the single stage converter can be solved, especially when the application of universal input is required. The design example of the proposed converter for 5 V 12 A application is presented. The design considerations and experimental results for the proposed converter are also shown. The experimental results show that the line current harmonics can meet IEC 1000-3-2 Class D requirements for the line voltage from 90 Vrms to 260 Vrms
