The present invention relates to a switched-mode power supply, and a mobile communication repeater system using a power factor correction circuit is applied, in particular, to a power factor correction circuit (PFC, Power Factor Correction) applied to the power supply (SMPS) in the mobile communication relay system by applying to reducing the apparent power it can be reduced to save energy. In this way, by a built-in power factor correction circuit to the power supply by reducing the load reactive power, with a minimum of input current waveform distortion caused by the power factor correction it is possible to ensure a high power factor in a wide output range, the output fluctuation of the power supply in which you can minimize the power factor varies. In addition, the output to the noise and AC input terminals for generating at by providing the EMI filter technology to ensure high power factor in a wide output range in order to minimize the input current waveform distortion generated in the capacitor, the power supply employing a power factor correction circuit It can reduce the EMI.
