The APFIC-115-3PH-12D-FT-C-G from SynQor is a Three-Phase Isolated AC-DC Converter that steps down an AC input voltage of 575 V to a DC output voltage of 12 V. It delivers an output power of up to 700 W and has an efficiency of 92%. This converter is designed for compatibility with commercial aircraft systems operating at variable frequencies. It offers minimal inrush current, balanced phase currents, and a high power factor while maintaining harmonic content within commercial aircraft standards. This converter minimizes the need for external output capacitance and can deliver full load current even during startup. It supports flexible scaling of power levels through parallel operation of multiple units.

This AC-DC converter supports features always-on standby power with AC and DC power good outputs, a PFC enable input, asynchronous serial data communication, and clock synchronization output for accurate performance. It integrates robust protection mechanisms such as output current limiting with auto-recovery, under/over-voltage auto-recovery, output over-voltage protection, and thermal shutdown with auto-recovery. This versatile converter meets electromagnetic interference (EMI) requirements when paired with additional EMI filters, which ensures stable and reliable performance in demanding aircraft environments. It is available in a module that measures 63.14 x 119.02 x 13.0 mm and is ideal for COTS components in airborne applications.
