The bang-bang controlled capacitor coupled converter (C{sup 3}) is described in this paper. Due to the converter`s inherent commutating property, the C{sup 3} can accommodate thyristors as well as high-power gate turn-off switches, due to zero-current switching transitions. The zero-current switching is achieved at no current stress increase, therefore, the topology is considered appropriate for high-power processing. DC and small signal ac models are derived for the bang-bang controlled C{sup 3}, a design procedure is proposed, and simulation results are discussed. Finally, oscillograms from a proof of principle prototype circuit are presented.
