Power modules for avionics

29 May 2019 Power Electronics / Power Management

SynQor announced its new AeroQor product line specially designed for commercial avionics. The AeroQor range is composed of high-efficiency, isolated power factor correction modules (APFIC) and AC filters specifically designed to meet the most stringent commercial airline specifications (RTCA/DO-160G, Boeing and Airbus).

This new product family offers wide frequency, single-phase and 3-phase, AC-DC converter solutions for all in-cabin power applications. Droop-share versions are available to combine multiple converters for higher-power applications. The power factor, THD, inrush and electromagnetic interference (EMI) characteristics of these converters allows them to meet some of the most stringent standards in the industry. The AeroQor modules are designed with a high level of documentation and full traceability.

The single-phase APFIC converters have a universal input – 85 to 264 VRMS – and a wide input frequency range of 4-63 Hz and 360-800 Hz. The input characteristics of the single-phase APFICs allow designers to meet several of the high and low input voltage transients while continuously delivering power. The power factor, THD and EMI characteristics of these modules have been optimised for low- and mid-power in-cabin applications.

The AeroQor product line also includes 3-phase, 115 VRMS line-to-neutral isolated power factor correction modules which are specifically designed to draw balanced currents from the source for higher-power applications. These high-efficiency modules have a wide frequency range, low THD, near unity power factor and low inrush, which are critical for commercial aircraft applications.

The AeroQor line of EMI AC filters are designed to mitigate EMI emissions from AC-DC converters in commercial aircraft. The combination of the AeroQor filters and converters allows designers to meet the toughest conducted and radiated emissions and susceptibility standards in the market.

Additionally, construction of the AeroQor modules allows them to meet the harsh environmental conditions demanded by the commercial airline market. The temperature range of these converters is -40°C to 85°C at an altitude of up to 21 336 metres. The modules also comply with the vibration, humidity and dust specifications required by commercial avionics.
