This paper introduces a new application of the previously introduced “Yeaman Topology” [1]. The main characteristic of this topology is to separate the output voltage regulation function from the bulk power conversion function, as it is used in DC/DC converters. Usage with single conversion PFC AC to DC converters confers the ability to efficiently regulate the line ripple on the output bus by over two orders of magnitude without needing to reprocess 100% of the energy coming from the previous conversion stage. The result is in an increase of power density, efficiency, and lower cost than a traditional post processing stage.
