Energy buffer device for an aircraft
First Claim
1. An electrical system for a passenger aircraft, comprising:
- an energy storage device coupled to a charge-electronics module, the charge electronics module being coupled to a generator of electricity, the energy storage device being coupled to the charge-electronics module by an energy feed line system comprising a first cross sectional area and a first length;
a consumer of electrical energy coupled with the energy storage device by an energy supply line system having a second cross sectional area and a second length;
wherein the energy storage device is arranged between the consumer and the generator,wherein the energy storage device decouples the consumer, such that all the power required for the consumer is drawn from the energy storage device and operation of the consumer does not directly place a load on the generator;
wherein the second cross sectional area is greater than the first cross sectional area and the second length is shorter than the first length; and
wherein the storage device provides a common voltage both to the energy feed line system and to the energy supply line system; and
the charge-electronics module controls the power that is fed to the energy storage device via the energy feed line system.

Abstract
An energy buffer device supplies energy to a consumer in an aircraft, and an electrical system for an aircraft. In one example, the device includes an energy feed device, an energy storage device and an energy supply device. The energy supply device may have line with a larger cross-sectional area than a corresponding line of the energy feed device. With the use of an energy buffer device, power may be switched on only for a short period of time. In addition, in case of a voltage breakdown in an on-board network, energy may be stored in an energy storage device. Supply of energy may thus occur over a short time at correspondingly high power, without placing a load on an on-board network or a generator.
