Redefining the sources of power

DC/DC Front-End Modules


Simplifying your future

GAIA Converter offers a complete range of Front-End elements to protect and adapt the power conversion stage. These Front-End Modules are designed to allow power engineers to ease the development of complex architectures and decrease the time-to-market of projects.

The Front-End performs input filtering and shaping of the input network, including the following functions:

  • EMI filter
  • Reverse polarity
  • Surge limiter
  • Under voltage limiter
  • Inrush current limitation
  • Hold up: Transparency during momentary input bus interruptions – drop outs
  • On/Off
  • Supply of additional signals to ensure perfect power supply management

GAIA Converter offers different types of modules as follows:

Single function modules
Multi function front-end modules
EMI Filters

GAIA Converter proposes a full family of state-of-the-art EMI filter modules to fulfill Electromagnetic Interferences (EMI) requirements for Aerospace/Defense applications in a very compact and low loss solution for applications requiring up to 35 amps of input current.

Our EMI Filter modules will help your power supply comply with major standards (MIL-STD-461 rev C, D, E and F – DO-160 rev C, D, E F and G).

All High-Rel filter performances are met across severe environments and operating temperatures of -40°C/+105°C (-55°C also available), and operating and storage temperatures of -55°C/+125°C.

The 100V filter range incorporates an inrush current limiter for the capacitors integrated in the filter. Combined with the “Input Bus Conditioners” modules, they allow the overall architecture of the power supply to respect the current inrush limits imposed by the D0160 and ABD100 standards.

High-Reliability Hold Up Modules​

The HUGD Series

GAIA Converter Hold-up devices are an alternative solution to the use of batteries or bulk capacitors to negate problems related to momentary input bus drop-outs.

The GAIA Converter HUGD series provides an alternative solution to reduce the amount of capacitance needed by charging the hold-up capacitor at a high voltage value. The device is connected between the input line source bus and DC/DC modules.
