Abstract :
In this paper, two generalized topologies of single-stage input-current-shaping (S/sup 2/ICS) circuits are derived: S/sup 2/ICS circuits with two-terminal ICS cells and S/sup 2/ICS circuits with three-terminal ICS cells. It is shown that most of the recently published S/sup 2/ICS circuits belong to either of the two generalized topologies. It is also shown that the two generalized S/sup 2/ICS topologies are functionally equivalent. Based on the generalized approach, a few new S/sup 2/ICS circuits are developed. Experimental results obtained on a selected pair of S/sup 2/ICS circuits with two-terminal and three-terminal ICS cells are also provided.
