N2 - Since the loss of input rectifying diode bridge in the conventional PFC converter reduces the efficiency, the bridgeless PFC converter has been proposed. The totem-pole bridgeless PFC converter is the most representative one. However the common mode noise current occurring around the input voltage zero-crossing brings severe EMI problem restricts its practical application. In order to improve noise performance, the noise mechanism should be investigated as the first step. In this paper, common mode noise current of totem-pole bridgeless PFC circuit has been analyzed. Furthermore, noise reduction based on the LC resonance is proposed. A 100V AC input, 395V dc output, 100kHz switching frequency experimental circuit has been built. By applying the noise reduction, the common mode noise can be suppressed efficiently.
