Flagship isolated ac/dc converter enables ‘world’s lowest’ profile power systems

The PFM VI Brick module incorporates power factor correction (pfc) and, with its Adaptive Cell architecture enabling high efficiency over worldwide ac mains, the PFM converter delivers 330W at 48V safety extra low voltage (selv) in a 9.5mm profile. It also provides isolation, voltage transformation and pfc regulation in a single stage using Vicor's high frequency soft switching technology. According to Vicor, its modular, scalable power component functionality supports efficient, cost effective power systems with 'N+1' redundancy. The PFM module is incorporate in a thermally enhanced, integrated heatsink rugged form factor and Vicor considers the converter to be its new flagship for its vision of a far reaching power component methodology. Tom Curatolo, Vicor's director, Applications Engineering told New Electronics: "This is the result of many years of R&D and the reaction at electronica has been one of amazement. We have made substantial investments and the PFM converter represents the first milestone in next generation ac/dc conversion. PFM modules will provide the 48 V 'hub' from which PRM regulators and VTM current multipliers can deliver superior end to end power system density, efficiency and flexibility." The PFM converter is available in the thermally enhanced, rugged VI Brick package.
