A totem-pole bridgeless power factor correction rectifier with the soft-switching capability is proposed in this article. The proposed converter utilizes an inrush current limiter (ICL) circuit, which is applied to satisfy the inrush current limit requirement to achieve the soft switching of main switches for high efficiency, so that high efficiency can be achieved by accomplishing the zero-voltage-switching operation. It can also relieve the reverse recovery problem of main switches, and minimize the soft-switching circuit by integrating the ICL circuit. Besides, the validity of the proposed converter is performed by the experimental results of a prototype converter with a 100-240 ${V}_{\text{AC}}$ universal line input and an 800-W (400 V/2 A) output.
