In this paper, the design procedure for 400W power factor correction(PFC) using UCC28050 is proposed for satisfying the international standards of input current harmonics, IEC61000-3-2. Comparing the continuous conduction mode(CCM) control method, the transition mode control method is very attractive for low power application. The PFC control IC, UCC28050, is adopted the transition mode control method up to 400W power consumption. The proto-type power factor correction circuit using UCC28050 is built and tested to verify the circuit operation.
