Gaia Simplifies Avionic AC-DC Power Supply Design with PFC Front-Ends

Gaia Converter has extended its HGMM ac-dc front-end module offering with the 150W half-brick. For all power needs from 35 to 350W or more, Gaia Converter’s 35W, 150W & 350W power factor correction (PFC) modules comply with the latest standards DO-160E, ABD100, AMD-24, and MIL-STD-704F.

This HGMM series offers a solution to comply with DO-160 & ABD100 Individual Current Harmonic (ICH) requirements in this power range. All 3 modules are available for 115Vac single phase and 360-800Hz wide frequency range with efficiencies as high as 93%. Input ranges of 47-440 Hz and universal 85-265 Vac / 45-65 Hz are also available.

The HGMM 35W front-end has 1500V isolation and 2 independent 17V outputs for compact low power designs in a standard 2″x3″ package. The HGMM Series of 150W and 350W front-ends are non-isolated half-bricks delivering a 375V output designed to be paired with isolated dc-dc modules such as the Gaia Converter high-voltage series (MGDS 75, 150 or 175W).

Additional key features include active inrush current limitation, output over load protection, short circuit protection, and an inhibit function. HGMS-150 and 350 models also provide a drive signal to control additional dc-dc modules, and a 7.5Vdc reference.
