Abstract

The invention provides a power supply system of a more-electric aircraft, and belongs to the field of aviation electrical systems. By adopting the power supply system architecture provided by the invention, the large-capacity and multi-load power utilization requirements of the advanced more-electric aircraft can be met, and under the condition of ensuring the redundancy of key power utilization equipment, measures such as energy storage and energy conversion can be reasonably utilized, so that the utilization rate of energy is improved.

Description

technical field [0001] The invention belongs to the field of aviation electrical systems, in particular to a power supply system for a multi-electric aircraft. Background technique [0002] In order to increase the driving power of the engine, reduce fuel consumption, and reduce the weight of aircraft cables, advanced aircraft such as A380, B787, and F-35 have realized the transformation from a multi-energy system to a multi-electric system in the field of energy function systems. Aircraft is the overall optimization of aircraft, and the electrification of aircraft is an inevitable trend of the new generation of aircraft. [0003] As an important component system of the aircraft, the power supply system is used to transmit and distribute the electrical energy provided by the generator to the electrical equipment of the aircraft, which is of great significance to the flight safety and task completion of the aircraft. The power system of the next generation of advanced multi-...
