A single-stage power-factor-correction ac/dc converter with a simple link voltage suppressing circuit (LVSC) for the universal Line application is proposed. A portion of the energy charged in a boost inductor is directly transferred to a load via LVSC without passing the link capacitor. Using simple circuitry, a low link voltage can be realized without input current deadbands at hue zero crossings, The proposed converter is analyzed and design guidelines for the proper operation of a converter are given. A universal input (90-265-V(rms)) prototype converter with 5-V 12-A output is implemented to verify performance. The experimental results show that the maximum link voltage stress and efficiency are about 447 V and 81%, respectively. The power factor is above 0.96 under the universal line condition when the load is higher than 30%.
