A comparison between two-commutation-cell multichannel and multilevel buck-derived topologies

In the frame of the development of a very high speed synchronous drive, a DC/DC converter is studied. In this context, this paper presents the comparison between two two-commutation-cell topologies. A multichannel and a multilevel converter are formally compared in terms of output current ripple reduction and control complexity. Moreover, partial experimental validations of the theoretical results are presented.
