摘要：

This paper reviews four different AC/DC converter topologies, and implement them to compare with each other. These selected circuits are analyzed with component quantity, current stress, and converter efficiency performances where these four circuits are selected to support the universal input (90 similar to 264 Vrms) and meet 1.3k Watt/400V DC output, 1 Watt/cm3 power density, and 12ms hold-up time. The density and component selection of DC bulk capacitors are considered to maintain the system operating normally i.e. enough hold-up time while the input AC line is lost. Finally, four 1W/cm3 power density prototypes of selected power converters were built for comparing those converters efficiency and total harmonic distortion (iTHD).
