Features & Benefits

and VI-J6x DC-DC Converters

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

The user need only provide external hold-up

capacitors, a few discrete components, and

a line filter (available from Vicor).
