Abstract

The bang-bang controlled capacitor coupled converter (C<sup>3</sup>) is described in this paper. Due to the converter's inherent commutating property, the C<sup>3</sup> 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</sup>, a design procedure is proposed, and simulation results are discussed. Finally, oscillograms from a proof of principle prototype circuit are presented
