What voltage does the Airbus A320's DC system operate at?
The Airbus A320 Electrical Power System consists of a three-phase 115/200 V 400 Hz constant-frequency AC system and a 28 V DC system. The system is composed of 2 engine generators and 1 APU generator. ATA Chapter 24 is titled Electrical Power, which covers AC and DC Generation, Load Distribution, and Emergency Power Systems.
What is Airbus A320 electrical power system?
The Airbus A320's electrical power system consists of a three-phase 115/200 V 400 Hz constant-frequency AC system and a 28 V DC system. It is composed of 2 engine generators and 1 APU generator, with each generator capable of providing AC power to all electrical bus bars. Some AC power is converted into DC power for certain applications.
How does the A320 electrical system work?
The first thing to do when learning the A320’s electrical system is to think of it as two distinct systems. There is an AC system and a DC system. The DC system is on the top and the AC system is on the bottom. You can see what I mean in this diagram. AC power is normally produced through the two ENG generators (GEN 1, GEN2), and the APU generator.
What is the main power supply system used in Airbus A320 family?
The main power supply system used in Airbus A320 family is 115/200 V, 400 Hz, three-phase constant frequency AC system. For the reliable and efficient electrical power supply system, electronic devices are used in aircraft. Integrated Drive Generator (IDG) and Generator Control Unit (GCU) are used in the generator control system of A320 family as the main parts.
Does Airbus A320 have AC or DC power?
A part of this AC power is converted into DC power through TRs for certain applications. The Airbus A320 electrical power system is constituted of 2 engine generators and 1 APU generator. Each generator can provide AC power to all electrical bus bars. In the event that normal AC power is not available, an emergency generator can provide AC power.
How does the A320 generate AC power without AC power sources?
If all AC power is not available, the electrical power system can invert DC power from the batteries into AC power. A320 is basically AC operated aircraft. Each IDG is controlled and monitored by its GCU. APU Generator can replace one or both main engine generators throughout the flight envelope.
