Product Overview

The high-boost HAM (Harmonic Attenuator

Module) is a universal AC input, PFC

front-end module that has been optimized

for use with Vicor’s V375 series of DC-DC

converters.

A single high-boost HAM may be used with

any combination of V375 series DC-DC

converters which are available in Micro,

Mini and Maxi packages with up to 600

Watts of output power. Versions without

internal diode bridges (HAMD and BAMD)

can be operated in parallel to provide power

expansion capability. The combination of the

high-boost HAM with V375 DC-DC

converters results in a power conversion

system with twice the power density, fewer

components and lower cost compared to

previous HAM-based solutions.

In addition, the high-boost HAM is fully

compatible with Vicor’s VI-26x and VI-J6x

series DC-DC converters. This gives

designers the freedom to choose from the

industry’s broadest selection of DC-DC

converters with outputs from 2 to 95 Vdc,

50 – 600 Watts. The user need only provide

external hold-up capacitors, a few discrete

components, and a line filter (available

from Vicor).
