  • Abstract This thesis studies the active power factor correction. In terms of converters, this thesis proposes a novel bridgeless interleaved buck converter for power factor correction, and uses digitalized average current control method to control the AC input voltage in positive half-cycle and negative half-cycle to achieve power factor correction. The interleaved architecture not only controls simplicity, but also can effectively reduce the component current stress at high output power, improve the high current resistance of the power components, the overlarge volume of the inductors, and the overlarge of output capacitors. This thesis actually produces a 480W bridgeless interleaved buck converter to verify whether the analysis and design considerations are reasonable.
    Unlike most power factor correction converters, which are used in the boost architecture, the bridgeless interleaved buck converter proposed in this thesis can be used in lower voltage applications, can reduce the values of output electrolytic capacitor and reduce the cost, and also because of the interleaved buck architecture, it can be applied to applications with high output power. The feasibility of the proposed architecture is verified by the experimental results in this thesis, and the total harmonic distortion and power factor of the input current can meet the international specifications.
