AC-DC front-end power module

6 February 2013 Power Electronics / Power Management

New from Vicor is the VI BRICK AC front-end module for high-density, high-efficiency AC to DC power conversion.

It is a complete AC–DC converter which operates over the universal AC input range of 85–264 V to deliver a fully isolated and PFC regulated 48 V output.

In a package measuring 95,3 x 48,6 mm and only 9,55 mm in profile, the module provides a power conversion density of 7,5 W/cm³ or 3,35 W/cm³ for a complete supply that includes all necessary components including hold-up capacitance.

With its integrated rectification, filtering and transient protection, the device enables customers to configure a complete front-end system that meets IEC 61000-3-2 harmonic noise and Class B EMI conducted emission limits while supplying 330 W to external output storage capacitance.

Featuring a proprietary double-clamp ZVS high-frequency switching topology, the module achieves consistently high efficiency – up to 92% – across its entire AC input voltage range, including operation down to 85 V a.c.

VI BRICK AC front-end modules are available to customers in consumer (-20°C to 100°C), telecom

(-40°C to 100°C) and military (-55°C to 100°C) temperature grades.
