Gaia Converter Introduces 60W DC-DC Input Bus Conditioner for Avionics/Military Applications

Gaia Converter introduces Hi-Rel Grade, DC/DC Input Bus Conditioner. The input bus conditioner FLHG-60 designates a 60 W input bus front-end that enables and eases the construction of power architectures for military and avionic 24 V and 28 V applications. The FLHG-60 includes:

An input EMI filter removing both common and differential conducted input noise to comply with MIL-STD-461 or DO160 Standards.
An input spike & surge limiter to comply with MIL-STD-704, MIL-STD-1275, ABD100 and DO160 over-voltages.
A reverse polarity protection.
A soft start function.
A hold-up function

Leveraging many functions, the FLGH-60 advantageously replaces all the input stage components of a power architecture such as filters, voltage limiter, diodes, inrush current limiter, and hold-up modules. As a single component, the FLHG-60 allows for a drastic reduction in space, as well as a simplification of the power architecture design. The FLHG-60 is designed to work with GAÏA Converter N input range of DC-DC converters.

Thanks to its wide input range, the input bus conditioner operates with all standard batteries voltages, according to 3 modes of operation:

Normal operation: when the input bus voltage is within its steady-state range, the FLHG-60 acts like a buffer transmitting the input power to the DC/DC architecture with low losses and conducted noise filtering.
High voltage transient operation: the FLHG-60 clamps the input transient, limiting its output voltage to the maximum voltage acceptable by the downstream DC/DC architecture.
Hold-Up operation: hold-up operation occurs when the input bus drops below the voltage at which the hold-up capacitor was previously charged. In this case, the FLHG-60 connects the downstream converter input bus to the charged hold-up capacitor to continue operation during the input bus drop.

The module is potted with a bi-component thermal conductive compound and packaged in a metallic case to ensure module integrity under severe environmental conditions.
