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).

TECHNICAL DESCRIPTION
The HAM (Figure 1) consists of a full-wave rectifier, a
high-frequency zero-current switching (ZCS) boost converter,
active inrush current limiting, short-circuit protection, control
and housekeeping circuitry. The incoming AC line is rectified
and fed to the boost converter. The control circuitry varies the
operating frequency of the boost converter to maintain the
output voltage of the HAM above the peak of the incoming
line, while forcing the input current to follow the waveshape
and phase of the line voltage. The AC input current follows the
voltage waveform and a power factor better than 0.99 is
achieved. Operating efficiency of the boost converter is
optimized at any incoming line voltage by an adaptive output
voltage (Figure 3) control scheme.

The output voltage of the HAM is a function of incoming AC
line voltage (Figure 3). On a nominal 115 Vac line, the output
voltage of the HAM is 280 Vdc — well within the input
operating voltage range of Vicor V375 DC-DC converters.
Above 180 Vac input, the output voltage linearly increases with
input voltage. At 230 Vac the delivered voltage will be
approximately 365 Vdc. For any given input line voltage, the
HAM maintains enough headroom between the output voltage
and peak input voltage to ensure high quality active power
factor correction without sacrificing operating efficiency.

PIN FUNCTION / DESCRIPTION
L1 and L2/N (HAM)
An appropriate line filter is required to limit conducted
emissions and ensure reliable operation of the HAM, see
page 8. Connect single phase AC mains to the input of the line
filter via a 10 A, 250 V fuse. Connect the output of the filter to
L1 and L2/N of the HAM. Do not put an X-capacitor across the
input of the HAM or use a line filter with an X-capacitor on its
output as power factor correction may be impacted.
+IN, –IN (HAMD, BAMD)
These pins are connected to the output of the external bridge
rectifier in HAMD / BAMD configurations (Figure 5).
GATE IN (HAM)
The user should not make any connection to this pin.
GATE IN (HAMD)
This pin provides line voltage envelope and phase information
for power factor correction. This connection must be made
through the synchronization diodes between the line filter
and bridge rectifier (Figure 5).
GATE IN (BAMD)
The Gate In pin is an interface pin to the Gate Out pin of a
HAMD or BAMD depending on configuration. The user should
not make any other connection to this pin.
GATE OUT
The Gate Out pin is a synchronization pin for HAMD/BAMD
arrays; the user should not make any other connection to this
pin.
+OUT and -OUT
Connect the +OUT of the HAM to the +IN of the respective
Vicor DC-DC converters with the recommended fuse. Connect
the -OUT of the HAM to the -IN of the converters. In addition,
an external hold-up capacitor of 1,000 µF with a minimum
voltage rating of 450 Vdc, is required (across the output of the
HAM) for 16 ms ride through time at full power (500 µF for half
power, etc). This capacitor must be in close proximity to the
HAM. Do not exceed 3,000 µF of total output capacitance. Lower
values of capacitance may be used for reduced hold up
requirements, but not less than 500 µF. Lower capacitance
values may degrade power factor specifications.

PIN FUNCTION / DESCRIPTION (CONT.)
A/S
The HAM provides a low voltage non isolated output Auxiliary
Supply (A/S) that may be used to power primary side control
and monitoring circuitry. This output is 19 – 23 Vdc, referenced
to -OUT, at 3 mA max. Do not overload or short this output as
the HAM will fail. A typical use for A/S is to power an optical
coupler that isolates the Power OK signal (Figure 6).
E/O
The Enable Output (E/O) is used to inhibit the DC-DC
converters at start up until the hold up capacitors are charged,
at which time Enable is asserted high (open state, Figure 8).
If the AC line fails, E/O goes low when the DC output of the
HAM drops below 250 Vdc.
The E/O pin ancillary circuitry illustrated in Figures 4 and 5
provides transient immunity. The illustrated circuitry is the
minimum required, see Figures 4 and 5.

PIN FUNCTION / DESCRIPTION (CONT.)
P/OK
Power OK is a monitor signal that indicates the status of the
AC mains and the DC output voltage of the HAM. P/OK is
asserted (active low) when the output bus voltage is within
normal operating range (>270 Vdc) and 20 – 25 ms after DC-DC
converters are enabled by the E/O signal of the HAM. This
provides sufficient time for the converters to turn on and their
output(s) to stabilize prior to P/OK being asserted, (Figure 9).
For momentary interruptions of AC power, the HAM will
provide at least 16 ms of ride through or hold up time (with
1,000 µF output capacitor). On loss of power or brownout,
+OUT
D
LOGIC
P/OK
(when the HAM output voltage drops below 270 Vdc) the
P/OK signal will go to an open circuit state (Figure 7),
signaling an impending loss of input power to the converter
modules. P/OK will provide power fail warning at least 1 ms
prior to converter shut down. When the HAM output voltage
drops below 250 Vdc the converters are disabled via Enable
Output (E/O).

A line filter is required to provide attenuation of conducted

line transients. It also presents a well defined high frequency AC
line impedance to the input of the HAM. To meet the listed
specifications, Vicor’s P/N 30205 line filter/transient suppressor
or equivalent must be used, see Figure 10. The addition of a
MOV external to this filter is required to meet normal mode

Figure 10 — Required HAM filter, Vicor part # 30205
For applications using HAMD + BAMD or where the user
desires to construct a custom HAM filter, the filter should be
designed following Figure 10, the schematic of Vicor’s P/N
30205 filter. The current carrying capability of the inductors must
be scaled proportionally to the number of HAM modules used.
Inductance values must be selected according to Table 1. These
limits are to ensure proper operation of the HAM and do not
guarantee a system will meet conducted emissions specifications.

Safety Notes
Each HAM, HAMD or BAMD module must be preceded by
a safety agency recognized fast-blow 10A 3AG fuse.
The HAM is not isolated from the line – either input or
output; a line isolation transformer must be used when
making scope measurements. HAMs do not provide input
to output isolation. Differential probes should be used when
probing the input and output simultaneously to avoid
destructive ground loops.
Protective Features
Over Temperature Shut Down
The HAM is designed to shut down when the temperature of
the baseplate exceeds 90°C. Do not operate the HAM above its
maximum operating temperature of 85°C.

Output Over Voltage Protection G
G
The HAM contains output over voltage
protection.
In the event
–IN
L2/N
the output voltage exceeds approximately 420 Vdc, the boost
will decrease to maintain 420 Vdc on the output. When the
peak of the AC line exceeds 420 V (approximately 293 Vac)
the boost will have been reduced to zero and the E/O line will
be pulled low shutting down the converters. Beyond this the
protection circuit will be enabled and the output voltage
will decrease.

Short Circuit Protection
The HAM contains output short circuit protection. Operation of
this function does not clear the input fuse and the output will
resume normal operation after removal of the fault.
A short period of time may be required to allow for cooling
of an internal temperature sensor.

Note: Mounting a High Boost HAM and Maxi, Mini or Micro DC-DC converter to the same heat sink will require the use of custom length standoffs or
a step in the heat sink mounting surface. This is due to a mechanical stack up difference between the HAM and Maxi, Mini, and Micro converters that
leads to incompatible baseplate height above the PCB.
