The Boost PFC interleaves circuit of inductance current continues double Boost DC/DC converter is discussed.Interleave Boost circuit is capable of reducing the output wave ripple,switching stress,inductance capability and EMI filter size.It improves power grade and efficiency,meanwhile,the separated inductors and coupled inductors used in the inter-leaved Boost PFC are analyzed respectively.Compared with separated inductors,the peak current in coupled inductors is large,the harmonic components of the input current are high,and the power factor is low.So a novel integrated inductor is applied,which is developed by using the Gyrator-Capacitor approach.The simulation and the experimental results show the drawbacks of coupled inductors are overcome by the integrated inductors.
