Aerospace and Military power supplies have always been subjected to stringent requirements including transients, spikes, EMI, hold-up, monitoring specifications. As a result majority of power supplies have been designed specifically with discrete components.
Since the beginning of the 90’s with the introduction of the COTS (Commercial Off-The-Shelf) philosophy in US and modular power architecture the use of standard modules has become of more importance to design complex power supplies.
The standard input voltages in Aerospace and Military applications are 24, 28, 270 VDC or 115 VAC within permanent variations, transients, spikes and drop-out to meet worldwide standards. EMI compliances are of primarily importance and are described in the widely used MIL-STD-461 or DO-160 standards.
To cope with these particular requirements, GAIA Converter proposes typical Off-The-Shelf modular power architecture :

• Qualified front filters to allow compliance with the MIL-STD-461, DO-160, ..., EMI requirements : FGDS series.

• Essential functions such as drop-out voltage recovery, transient and spike protections as per MIL STD-704, MIL-STD-1275 or DO-160 are handled by standard “Pre-Regulator” front-end product : PGDS series.

• Power factor corrected 115VAC front-end allow easy board intermediate bus configurations : HGMM series.

• Monitoring and hold-up functions are provided by GAIA Converter hold-up module to sustain bus losses together with fault and advisory signals : HUGD series.

• For the heart of the power system, GAIA Converter proposes a complete series of low profile, cost-effective and high performance DC/DC modules that come in multiple combinations of input voltages, output possibilities and power ratings : MGDM series.

Whatever your power system’s need, GAIA Converter has a modular architecture using standard products to provide an instant solution to a wide range of applications from on-board computers, man-machine interface, communication systems, ...
