VI-HAM Protection Features
(continued)
Inrush Current Limit
The VI-HAM contains inrush current
protection in the form of a PTC and a
shunt device. The same PTC is used for
overcurrent protection on the output.
Input Transient Overvoltage Surge Protection
This function is included in all VI-HAM
compatible filters. If any other filter is used
this function must be provided externally,
typically by a transient suppressor.
All VI-HAM configurations must be
preceded by an appropriately rated fast-blow
3AG fuse ahead of the line filter. This fuse
would be a 10A for a single VI-HAM
connected to line. For fusing information on
other VI-HAM configurations, please
contact Vicor’s Application Engineering
Department.
VI-200 Family
VI-J00 Family
Compatible Modules
Over the full range of input voltages (85 to 264 Vac),
the output varies from 260 to 415Vdc. Therefore
the modules used with the VI-HAM are from the
VI-260 and VI-J60 families.
When ordering add the prefix VI- to the part
number below; i.e., VI-260-CU.

Filter Requirements for the VI-HAM
The VI-HAM requires an external filter to meet international standards for conducted
EMI/RFI emissions. P/N 07818 (for use up to 600W) incorporates transient protection for
compliance with IEC 61000-4-5 Level 3 and meets conducted emissions standards
EN55022 and FCC Part 15 Level A (minimum loading of 150W required).
VI-HAM Configurations
VI-HAM-CM
VI-HAMD-CM Driver HAM: No internal bridge rectifier or synchronization diodes.
VI-BAMD-CM Booster HAM: Companion module to VI-HAMD-CM used for
additional output power. No internal bridge rectifier.
Use the VI-HAM-CM for applications requiring up to 600W from the front end.
For applications in excess of 600W, it is not possible to simply parallel two driver
VI-HAMs due to conflicting control loops. Gate Out to Gate In connections on
respective driver/boosters are used to ensure that the power train of the VI-HAMs
current-share. However, this does not ensure that the diodes in the lower half of the
bridge rectifier will current-share. A solution for this situation is illustrated (see Fig. 8).
A solution to bridge rectifier current sharing issues is to remove the bridge rectifier
from each VI-HAM and use one diode bridge sized to handle the entire load.
Approximately 25% of the heat is removed from the VI-HAM in this approach; use a
VI-HAMD-CM with one or more VI-BAMD-CMs. Note: Synchronization diodes are
required when using this approach (see Fig. 10).
