Abstract :
A systematic analysis of line current distortions of the DCM/CCM boundary boost PFC converter due to valley switching and switching-frequency limitation is provided. Closed form expressions for the line current are derived. It is shown that if the switching frequency is limited and valley switching is not maintained, the line current is more distorted with voltage mode control than with current mode control. The effects of line current distortions are demonstrated with both simulation and experimental results.
