This paper presents two-phase flyback converter based on interleaved control, so as to upgrade the output power and to improve the power factor. Such interleaved control is realized via the proposed control rule. In this paper, the proposed control scheme for a 144W two-phase flyback converter, which has the rated input voltage of 110Vrms and the output voltage of 48V, is implemented by logic circuits. And, some simulation and experimental results are provided to demonstrate the effectiveness of the proposed control strategy.
