| Abstract |
This paper shows an average current predictive control algorithm for Power Factor Correction (PFC) con- verters operating across all conduction modes, namely Continuous Conduction Mode (CCM), Discon- tinuous Conduction Mode (DCM) and the continuous changing between both operational modes known as Mixed Conduction Mode (MCM). The proposed control software allows for the bumpless transfer between conduction modes and large input voltage range. No conduction mode detection or duty-cycle feed-forward selection is required as in other typical PFC control schemes. The proposal is simplified to an arithmetic ideal feed-forward duty cycle calculation based on measured current and voltage samples. |
