A Step Up/Down Power-Factor-Correction Converter with Modified Dual Loop Control
Energies, 2020 A step up/down AC/DC converter with modified dual loop control is proposed. The step up/down AC/DC converter features the bridgeless characteristic which can reduce bridge-diode conduction losses.

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.
