Vicor Corporation Introduces High Density AC-DC Front-End Power Module
Vicor today announced the VI BRICK AC Front End module for high, density, high efficiency AC to DC power conversion. This new module is a complete AC–DC converter which operates over the universal AC input range of 85-264V to deliver a fully isolated and PFC regulated 48V output. In a low profile package measuring 3.75 x1.91 inches (95.3mm x 48.6mm) and only 0.38 inches (9.55 mm) in height, the AC Front End module provides a power conversion density of 121 W/in3 (7.5W/cm3) or 54 W/in3 for a complete supply that includes all necessary components including hold-up capacitance.
EverWith its proprietary Double-Clamp ZVS high switching frequency topology, the AC Front End module achieves consistently high efficiency – up to 92% – across its entire AC input voltage range, including operation down to 85VAC and cuts power losses by more than 50% compared to competing offerings. The AC Front End also simplifies the customers’ cooling requirements, reducing both the size and cost of cooling components.
“From the wall plug to the point of load, Vicor provides low profile, high density, high efficiency power components that enable the most versatile and tightly-integrated power systems on the market today,” said Rob Russell, Vice President, Brick product line, Vicor. “This AC Front End module based on performance- proven VI Chip technology now expands Vicor’s brick product line into AC-DC applications.”
The new VI BRICKAC Front End module is compatible with a wide variety of downstream
DC–DC power conversion components including Vicor’s comprehensive portfolio of high-density, high efficiency, VI Chip and VI BRICK converters. When used with downstream DC–DC converters which support secondary-side energy storage and efficient power distribution, the AC Front End module provides superior power system performance and connectivity from the wall plug to the point of load and enables customers to design reliable and cost-effective power systems.
