| Abstract: | According to the output characteristics of the special generator for full authority digital electronic control (FADEC) system of aero-engine, a constant current variable frequency control AC/DC (alternating current/direct current) transform technique based on current feedback was proposed with purpose of accommodating to the wide-range-output of the special generator, so as to meet the power supply requirements of FADEC system. The control strategy, topological structure and operation principles were embodied along with the overvoltage test and protection design. Experiments results prove the reliability of the converter in full temperature range from -55℃ to 125℃, and compliance with the stipulations of national military standard GJB181A covering aircraft electric power characteristics. Research findings has been successfully applied in certain aero-engine numerical control system and validated in both bench test and flight platform experiment. |
