Research on design and verification of aircraft in-seat power supply system

Abstract

Abstract:

It is a tendency to use PED (portable electronic device)including laptops on board of civil aircraft. The design and verification of in-seat power supply (ISPS)and its management control unit (MCU)for PED power supply are discussed. The SPWM pure sine wave technology has been adopted to convert 115/200V400Hz aircraft power to AC 110 V 60 Hz and DC 5 V(USB). Thus,THD is reduced and convert efficiency is increased. Lots of tests verifies the design,showing that the power is reliable,safe and highly efficient. PMA certificates are obtained from CAAC airworthiness authority.

Key words: civil aircraft, PED power supply, SPWM, verification, PMA certificate

CLC Number:
