Wj. Ho et al., OPTIMIZING SINGLE-PHASE PFC PRE-STAGED AC DC/AC TOPOLOGY VIA COMMON-NEUTRAL CONNECTION/, Electronics Letters, 32(17), 1996, pp. 1529-1530
A new topology for the single-phase PFC-pre-staged AC/DC/AC converter
is presented. The introduction of a common-neutral connection simplifi
es the conventional connection of an AC/DC/AC structure, and gives a n
ew topology that still has good performance, conforms with output safe
ty regulations and has other advantages such as requiring fewer power
devices and having lower conduction losses.
