Abstract :
A single stage isolated PFC converter is obtained merging flyback and forward topologies. Thus, the flyback section allows power transfer while the line rectified voltage is not high enough to enable the forward stage operation. By this way, optimal correction is feasible. Also, this approach allows sharing of the transformer and the power transistor
