Vicor Corp. (Andover, MA) announced its high-boost VI-HAM (harmonic attenuator module), which is a universal ac-input, power-factor corrected, front-end module that has been optimized for use with Vicor’s V375 Series of dc-dc converters. The VI-HAM consists of a full-wave rectifier and a zero-current switching boost converter with active inrush current limiting, over-temperature and short-circuit protection, and control.
A single high-boost VI-HAM may be used with any combination of V375 Series dc-dc converters (available in quarter-brick, half-brick and full-brick packages) up to 600 W, resulting in a power conversion system with twice the power density, fewer components, and lower cost compared to previous VI-HAM based solutions. Parallelable versions are also available for applications requiring over 600 W of output power.
In addition, the high-boost VI-HAM is fully compatible with Vicor’s VI-26x and VI-J6x Series dc-dc converters giving the freedom to choose from a broad selection of dc-dc converters with outputs from 2 Vdc to 95 Vdc, at 50 W to 600 W.
Pricing for the high-boost VI-HAM modules is the same as for the existing VI-HAM family (as low as $99 in quantities of 5,000), and they are available from stock.
