An Induction Generator based AC/DC Hybrid Electric Power Generation System for Additional Electrically Powered Airliner

Abstract

For an additional aircraft power system, both  AC and DC power having high voltage levels are required.  with various flight loads. This paper introduces an induction  generator based on AC / DC hybrid MEA power generation  system. In the proposed system structure, a high-speed  generator/generator and a low-speed generator are fitted with  high pressure (HP) and low pressure (LP) of the spools of the  engine, respectively. In production mode, all alternating AC  power is generated by the HP generator while the DC power  supply is supplied by both HP and LP generators. The control  system is designed to control the AC power supply and direct  the DC power supply between the two generators. The  proposed AC / DC-based induction generator system results  in reduced demand for computer hardware compared to the  AC and DC production systems.
