The GAIA Converter HGMM-350 universal input
module HGMS-350-Y-T designates a non isolated
AC/DC power factor corrected module designed
to be compatible with the single phase input
bus 115/230VAC 50/60Hz frequency.
The modules accept an AC input voltage ranging
from 85Vac to 265Vac and include active power
factor corrector that enables a very low level of
current harmonic distorsion.
The HGMM-350 is compliant with numerous
military standards requirements among them
with :
• the US military standard MIL-STD-1399A/B :
- permanent input range : 107-123Vac
- transient : 92Vac/2s - 138Vac/2s
• the US military standard MIL-STD-704E/F :
- permanent input range : 108-118Vac
- transient : 80Vac/10ms - 180Vac/100ms
• the US military standard MIL-STD-1399

Non Isolated Output
Metallic Case
The HGMS-350-Y-T module includes a soft start
an active inrush current limitation, a permanent
short circuit protection and an inhibit function.
The soft-start/active current limitation eliminates
inrush current during start-up, the short circuit
protection protects the module against short-
circuits of any duration by a shut down and
restores to normal when the overload is removed.
The HGMS-350-Y-T output voltage is set to 420Vdc
compatible with GAIA Converter high input vol-
tage series of DC/DC converter and operates
with a hold-up capacitance to allows transparency
time and ripple reduction.
The design has been carried out with
surface mount components and is manufactured
in a fully automated process to guarranty high
quality. Every module is tested with a Gaïa
Converter automated test equipment. The mo-
dules are potted with a bi-component thermal
conductive compound and packaged in a metalic
case to ensure the module’s integrity under high
environmental conditions.

3-2 Total Harmonic Distorsion Factor (THD) Characteristics
The Total Harmonic Distorsion (THD) is the ratio between
the total energy contained in all row harmonic (except
fundamental harmonic) by the fundamental harmonic wave.
The following curves represent the Total Harmonic Distorsion
Factor (THD) for the HGMS-350-Y-T at 115Vac/60Hz and at
230Vac/50Hz.
3-1 Power Factor (PF) Characteristics
The Power Factor (PF) is the ratio of the «real» power to
the apparent power.
The apparent power is the product of the rms volts measured
with one meter and the rms amps measured with another
meter (value in VA).
The «real» power is the time average of the instant product
of voltage and current (value in Watts).
The «real» power cannot be measured directly with 2 meters
as it has to integrate the phase shift between voltage and
current. This phase shift between voltage and current
reduces the effective power delivered.
The Power Factor (PF) is a measure of the effectiveness
with which an AC load can extract the usable power from
an AC source.

The HGMM-350 universal input series maximum baseplate temperature must not exceed 115°C and is a function of output
load as described in the following figure :
Heat can be removed from the baseplate via three basic
mechanisms :
• Radiation transfert : radiation is counting for less
than 5% of total heat transfert in majority of case, for
this reason the presence of radient cooling is used as
a safety margin and is not considered.
• Conduction transfert : in most of the applications,
heat will be conducted from the baseplate into an
attached heatsink or heat conducting member; heat is
conducted thru the interface.
• Convection transfert : convecting heat transfer
into air refers to still air or forced air cooling.
In majority of the applications, heat will be removed from
the baseplate either with :
• heatsink,
• forced air cooling,
• both heatsink and forced air cooling.
To calculate a maximum admissible ambient temperature
the following method can be used.
Knowing the maximum baseplate temparature Tmaxbaseplate
of the module, the power used Pout and the efficiency η:
• determine the power dissipated by the module Pdiss
that should be evacuated :
Pdiss = Pout(1/ηη
ηη
η - 1) (A)
• determine the maximum ambient temperature :
Ta = Tmaxbaseplate - Rth(b-a) x Pdiss (B)
where Rth(b-a) is the thermal resistance from the
baseplate to ambient.
This thermal Rth(b-a) resistance is the summ of :
• the thermal resistance of baseplate to heatsink
(Rth(b-h)). The interface between baseplate and
heatsink can be nothing or a conducting member, a
thermal compound, a thermal pad.... The value of
Rth(b-h) can range from 0.4°C/W for no interface down
to 0.1°C/W for a thermal conductive member inter-
face.
• the thermal resistance of heatsink to ambient air
(Rth(h-a)), which is depending of air flow and given
by heatsink supplier.

11- Description of Protections
11-1 Output Short Circuit Protection (SCP)
The short circuit protection device protects the module
against short circuits of any duration. It operates in
«hiccup» mode by testing approximately every «recovery
time» (typically 1.1s) if an overload is applied with a
detection time lower than 70ms and restores the module
to normal operation when the short circuit is removed.
11-2 Output Over Power Protection (OPP)
The HGMM-350 incorporates a foldback power limit and
protection circuit. When the output power reaches 1,5
time it’s full-rated power, the output voltage falls along
the foldback line as described in the figure herein. When
the output voltage decreases below 40% of VOnom the
module fall in a hiccup mode and activates the short cir-
cuit protection. The module restart automatically to nor-
mal operation when overcurrent is removed.
11-3 Over Temperature Protection (OTP)
A thermal protection device adjusted at 115°C (+/-5%)
internal temperature with 10°C hysteresis cycle will inhibit
the module as long as the overheat is present and restores
to normal operation automatically when overheat is
removed. The efficiency of the OTP function is warranty
with the module mounted on a heatsink.

12- Description of Functions
12-1 On/Off Function
The control pin 4 (On/Off) can be used for applications requiring
On/Off operation. This may be done with an open collector
transistor, a switch, a relay or an optocoupler.
• The converter is disabled by pulling low the pin 4.
• No connection or high impedance on pin 4 enables the
converter.
By releasing the On/Off function, the converter will restart
within the start up time specifications given in table section 4.
12-2 «Drive» Function
The HGMM-350 with it’s 420Vdc output has to be used in
conjunction with a hold-up capacitor and a companion isolated
module MGDM-150-T series of GAIA Converter.
The drive function is a signal that controls the start-up and
the stop of the the companion module.
At start-up of the HGMM-350, the drive function is in low
impedance status preventing the companion module to start
as long as the hold-up capacitor is not charged to reach
420Vdc.
When the capacitor reaches 90% of it’s charge, the drive si-
gnal is released allowing the companion module to start-up.
If the HGMM-350 is powered-down in case of input bus failure
for example, the hold-up capacitor will discharge to maintain
the companion module in operation down to a voltage of
150Vdc then the drive signal will stop the companion module
to operate with a low impedance signal.

The signal «REF» is an auxiliary voltage of 7.5Vdc +/-2%
referenced to Go. It can provide a maximum current of 1.5mA.
It is recommended to add a 100nF decoupling capacitor when
this signal is used. When the module is turned off or when
there is an input power interruption, the signal Vref drops to
0Vdc.
12-4 «PFCSH» Function
The HGMM-350 features a share function to parallele 2
modules up to 700W power.

13- Application Notes
13-1 Connections
The HGMM-350 has to be used in conjunction with an
external hold-up capacitance accross the outputs to limit
the output voltage ripple.
A low ESR capacitor is suggested to minimize the ripple
and losses. It’s voltage rating has to be chosen according
to the maximum permanent & transient output voltage
specified.
The right charts specifie for a given capacitance value the
resultant output ripple value for the HGMS-350-Y-T.
This hold-up capacitance is also used to achieve a
transparency time. The capacitor value range is given in
table section 3.
The HGMM-350 output voltage is a high and non isolated
voltage of 420 Vdc.
To achieve usual low voltages such as 5, 15 .... or 28 Vdc,
the HGMS-350 module has to be connected with a GAIA
Converter compatible companion module. Companion mo-
