Abstract—Traditional power factor correction (PFC) circuit, which limits the power density is often passive components. With the development of power electronics technology, high-frequency, modular, miniaturization is the inevitable trend of development. In pursuit of efficiency and the use of bridgeless topology brought about more complex control method compared with the conventional topology. In this paper a three-phase bridgeless Flyback PFC topology is studied, the use of three-phase input, which greatly reduce the storage capacity of the capacitor, working in discontinuous current mode (DCM), using fixed duty cycle control to achieve unity power factor, with a simple and efficient, simple control advantages. The simulation results from a 250W universal input prototype are given to verify the effectiveness of the analysis.
