FEBFAN9611_S388V1, Evaluation Board based on FAN9611 400W Interleaved Dual-BCM PFC Controller

FEBFAN9611_S388V1, Evaluation Board for the FAN9611 interleaved dual Boundary-Conduction-Mode (BCM) Power-Factor Correction (PFC) controllers operate two parallel-connected boost power. Interleaving extends the maximum practical power level of the control technique from about 300W to greater than 800W. Unlike the continuous conduction mode (CCM) technique often used at higher power levels, BCM offers inherent zero current switching of the boost diodes (no reverse-recovery losses), which permits the use of less expensive diodes without sacrificing efficiency. Furthermore, the input and output filters can be smaller due to ripple current cancellation between the power trains and doubling of effective switching frequency
