A single-stage power factor correction AC/DC converter with a simple link voltage suppressing circuit (LVSC) for the universal line application is proposed, using this simple circuit, a low link voltage can be reahzed without deadbands at line zero-crossings The proposed converter is analyzed and a prototype converter with 5V, 12A output is implemented to verify the performance, The experimental results show that the link voltage stress and and efficiency are about 447V and 81%, respectively.
