Abstract :
This paper proposes a novel adaptive master-slave interleaving method for boundary conduction mode (BCM) PFC converters. The natural period of every switching cycle of each channel is measured and compared to adaptively determine the master converter. The proposed method guarantees stable interleaving operation in any transient. The proposed method has been implemented and tested on a 400W interleaved BCM boost PFC prototype converter with a dedicated control IC.
