LE HAILLAN, France – Gaïa Converter in Le Haillan, France, is introducing four AC/DC converter front-end power electronics modules for use in centralized power architectures with point-of-load converters or isolated DC modules.
The AC/DC power-factor-corrected front-end modules are compatible with common airborne AC input bus voltages and variable frequencies for aircraft and avionics applications. Each device has a power input of 115 volts at 400 Hz. power module 30kw
The HGMM-35 AC/DC converter has maximum power of 35 Watts, is isolated, and has two 17-volt DC output voltages. The HGMM-50 has maximum power of 50 Watts, is isolated, and has two 17-volt DC output voltages. The HGMM-150 has maximum power of 150 Watts, is not isolated, has an output of 375 volts DC. The HGMM-350 has maximum power of 350 Watts, is not isolated, and has an output of 375/420 volts DC.

All of the modules meet the stringent requirements of DO-160, ABD-100, and MIL-STD-704 specifications. The AC/DC front-end modules have a soft-start, active current limitation, short-circuit protection, and inhibit function.
The soft-start/active current limitation prevents inrush current during startup. The short-circuit protection safeguards the module from short circuits by shutting down and restoring to normal when the overload is removed.
Front end series under 50 Watts offer two isolated low voltage outputs. Series above 150 Watts provide non-isolated high voltage output.
