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 control scheme.
VxHAMxM
The output voltage of the HAM varies as a function of incoming
AC line voltage, Figure 3. On a nominal 120V
AC
line the output
voltage of the HAM is 260V
DC
— well within the input operating
voltage range of Vicor VI-26x and VI-J6x converters. As input
line increases, so does the HAM output voltage; at 220V
AC
the
delivered voltage will be about 350V. 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 unnecessarily 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 10A,
250V 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 1,000µF with a minimum voltage rating
of 450V
DC
, is required (across the output of the HAM) for 16ms
ride through time at full power (500µF for half power, etc). This
capacitor must be in close proximity to the HAM. Do not exceed
3,000µF of total output capacitance.
Lower values of capacitance may be used for reduced hold up
requirements, but not less than 500µF. Lower capacitance values
may degrade power factor specifications.
