| Abstract: | A lossless snubber circuit is introduced to the conven- tional power factor correction (PFC) circuit.The lossless snub- ber is employed to decrease the switching stress and EMI,so the switch condition is improved.The operational principle is analyzed in detail,a 3kW single-phase PFC circuit based on UC3854BN was designed,the dual-loop control system and av- erage-current control were adopted,and the good performance was verified experimentally. |

| Keywords: | power factor correction average-current control lossless snubber switch stress |
