Embodiment Construction

[0024] The present invention is an aircraft power management control device with small size, light weight (1.5Kg) and low power consumption, which belongs to the independent aircraft power management system and is a completely independent subsystem with independent processor and software. The data lines and power lines are connected to aircraft battery packs, generators, converters and other equipment.

[0025] According to the design requirements of the aircraft power supply system (including: aircraft DC power supply system and aircraft AC power supply system), combined with the development trend of aircraft power supply systems at home and abroad, the architecture of the power management control device of the present invention is determined ( figure 1 ), which is a part of the entire aircraft power system architecture. The on-board aircraft power system switching and analog data are collected in parallel in real time through the FPGA. According to the design requirements, th...

Abstract

The invention relates to the aviation power electronic technical field, and relates to a power supply management control device; aiming at airplane multi-power equipment complex structures, the power supply management control device can uniformly manage and control the power equipment; data acquisition and logic operation are employed so as to charge and discharge a battery pack 40 and a battery pack 25; the power supply management control device can control the redundancy of no.1 and no.2 stationary current transformers, can control switching between airborne power supply and ground power supply, can control left and right hinge power supply transitions, can control flight control system emergency power supply transitions, and can control a single generator power supply mode, thus improving the airplane multi-power equipment complex structures, reducing airplane weight, reducing cost, and improving airplane reliability and performance indexes.

Description

technical field [0001] The invention relates to the technical field of aviation power electronics, and relates to a power supply management control device, which is especially suitable for trainer aircraft. Background technique [0002] As aircraft are increasingly dependent on electrical support, electrical systems have made significant progress in the past few years; aviation power is the second largest energy source for aircraft and occupies a core position in aircraft electrical systems. Power refers to power General term for system and power distribution system. [0003] At present, with the great increase of airborne electronic equipment, higher requirements are put forward for the power and security of the aircraft power system. At the same time, due to the huge power supply system of the aircraft, there are many power supply equipment, such as: low-voltage DC system, variable frequency AC system, constant speed and constant frequency AC system, variable speed and co...
