White Paper: A Novel Approach to Industrial Rectifier Systems

August 31, 2014

PCIM White PaperAC-DC converters for industrial applications have been relying on double-stage architecture for quite a long time. A non-isolated, single- or three-phase, single- or multi-level stage typically feeds an isolated DC-DC stage, with capacitors between the two stages providing the necessary energy storage.

The need for high efficiency and high density has determined the evolution of distributed power systems toward architectures that employ optimized power components. Among those power components, fixed-ratio bus converters have been developed to provide state-of-the-art performance, including components capable of 300-400V DC input that provide isolated, Safety-Extra-Low-Voltage (SELV) output.

This paper, presented at PCIM 2014 by Maurizio Salato, director, power systems engineering at Vicor, proposes a new AC-DC system architecture based on fixed-ratio bus converters. System functions are described and analyzed for the classic as well as the proposed approach; benefits, trade-offs and design methodology for the novel architecture are also discussed.
