| Abstract: | In this paper, the reason producing harmonic and the importance of power factor correction are clarified. The principles of Boost PFC converter are summarized and interleaved active power factor correction under CCM mode is presented. A power factor corrector is realized by two-phase interleaved CCM PFC controller UCC28070 of Texas Instruments Company. Power factor correction is achieved by this power factor corrector while the current harmonic is greatly reduced and the input power factor is improved. |
