Abstract :
Interleaving architecture extends high performance, low cost, transition mode PFC to higher power levels. Because the existing master slave interleaving control requires a slave channel operating in DCM mode, switching loss and EMI noise are increased. In this paper, a novel interleaving control method is proposed without using the master slave concept. The proposed method is able to realize 180 degrees phase-shift as well as true transition mode operation to achieve the optimal system performance.
