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.
4.6 x 2.4 x 0.5 in
(116,8 x 61,0 x 12,7 mm)
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).
