Loss comparison of different nine-switch and twelve-switch energy conversion systems [PDF]
, 2014 Nine-switch converter is a recently proposed reduced-switch equivalence of the twelve-switch back-to-back converter. The usual expectation is thus for the nine-switch converter to face some switching constraints and hence performance tradeoffs.
