NEXEYA has developed a new family of three-phase switched-mode power supply without neutral from 5 KW to 30 KW dedicated to mission-critical environments by optimizing:
The harmonic rate,
The COS phi,
The weight/power ratio,
The Heat dissipation via a high efficiency solution,
Designed to be qualified DO 160 / MIL STD, these solutions are modular, compact and secure. An innovative switching concept allows an overall efficiency of more than 95%, an availability of 5. 10-7 / Flight hour ( 5 + 1 redundancy ) with an exceptional weight/power ratio of 0.4 kg / KW, insulation and filters included, for a power of 15 KW.
Variable Frequency 320-800Hz Galvanic Isolation
0,4kg/kW for 15 kW Forced Cooling
Shared Output Current 5+1 Redundancy
0,5 L/ kW for 15kW
Low Harmonic Distortion Ratio
The implemented solution converts the AC three-phase voltage from an aircraft network to galvanically isolated 28 VDC. The characteristics are improved thanks to the use of different innovative technologies such as SIC and GAN.
Other solutions are in development for marine applications.
