Abstract

Most of the power factor regulator topologies in continuous conduction mode result in bulky magnetics, and in discontinuous conduction mode result in high harmonic content. To solve these problems a Cuk topology is presented in discontinuous conduction mode (DCM) with coupled inductors for power factor regulation, the unique feature exhibited by the converter that makes the converter better than the other converter in DCM operation for power factor regulation. Inductive coupling is used to transfer the ripple from the input to the output side thereby reducing the switching harmonics in the line current. Experimental results obtained on a 500 W prototype are also presented.
