Title: Intermediate bus architecture: A system’s perspective
Abstract: Four basic intermediate bus architectures are presented. Salient features for each system are discussed in detail. They cover input power stage, bus voltage level, output power stage, output regulation, multiple outputs, thermal property, system stability, and output impedance. Design tradeoffs are also presented to guide practical designs. It is concluded that the double regulated intermediate bus architecture has the best efficiency, regulation, thermal, and stability performances. Engineering hardware for the double regulated intermediate bus achieved a record efficiency of 99%. Recent advancement in switched-capacitor-based unregulated intermediate bus may provide higher power density.
