Abstract：On-board power systems of large aircraft are quickly moving from constant frequency (CF) AC to variable frequency (VF) AC systems or a hybrid system configuration. Replacing CF AC systems by VF AC systems will reduce system weight, volume, costs; and improve overall system efficiency. A future VF-power system architecture is presented. Architecture optimization is based on the cost index minimization of the total kVA throughput times the number of stages of conversions. New requirements and challenges for the design of new equipments and subsystems are also discussed.

Key words： Large aircraft power systems distributed variable-frequency systems architecture optimization for higher total efficiency minimization of total power loss of multiple-stages AC-AC converters
