Current-Doubler Rectifier Reduces Ripple Current
The current-doubler rectifier is a popular alternative for the output stage of a buck-derived power converter, which would otherwise use a conventional center-tapped transformer with secondary-side, full-wave rectification. Power topologies within this class include the push-pull, half bridge and full bridge. Many advantages can be gai...
