1- General
The GAIA Converter HGMM-35 series designates
a family of active power factor corrected AC/DC
isolated modules designed to be compatible with
the latest airborne input bus with single phase
115VAC/400Hz variable frequency.
This module accepts a variable frequency input
from 360 to 800 Hz in the range of 95 to 140Vac
and an active power factor that enables a very
low level of current and voltage harmonic
distorsion over the entire frequency excursion.
The HGMM-35 series is compliant with numereous
avionics/military standards among them with :
• the latest Airbus standards ABD100 :
- permanent input range : 108-122Vac
- transient : 71Vac/15ms - 180Vac/100ms
- variable frequency : 360 - 800 Hz
- power factor : > 0,95
• the international standard DO-160D :
- permanent input range : 100-122Vac
- transient : up to 180Vac/100ms
• the US military standard MIL-STD-704E :
- permanent input range : 108-118Vac
- transient : 80Vac/10ms - 180Vac/100ms
The HGMM-35 series includes a soft start, a per-
manent short circuit protection and an inhibit
fuction.
The soft-start allows current limitation and
eliminates inrush current during start-up. The
short circuit protection completely protects the
module against short-circuits of any duration by
a shut down and restores to normal when the
overload is removed.
The HGMM-35 series includes a model available
with dual 2 x 17 Vdc outputs serialisable/
parallable 17 or 34 Vdc to optimize the use of
hold-up capacitance.
The HGMM-35 series has to be used as front-end
in conjunction with a capacitance for hold-up
and DC/DC modules at the output.
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- Electrical Characteristics (continued)
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).
Hi-Rel
Grade
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.

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 HGMM-35 Total Harmonic
Distorsion Factor at frequency of 400 Hz and at frequency
of 800 Hz.

3-3 Individual Current Harmonic Distorsion Characteristics
The individual current harmonic distorsion requirement is
a very specific requirement defining for each harmonic
row, the maximum admissible current in all functionning
conditions.
This requirement induced the Total Harmonic Distorsion
Factor (THD) defined above.
These requirements are defined by the aircraft
manufacturers in proprietary (and confidential) standards.
GAIA Converter HGMM series comply with individual current
harmonic distorsion requirements of :
• AIRBUS ABD100 section 1.8 with specific limits on :
odd non triplen and odd triplen harmonics
even 2 & 4 and other even harmonics
• BOEING D6-44588 with specific limits on
odd non triplen and odd triplen harmonics
even harmonics
