摘要:

在民航客机上使用包括便携式计算机在内的个人移动电子设备(PED)是必然趋势。讨论了专门为PED供电的飞机座椅电源(ISPS)及其控制器(MCU0设计和验证;采用SPWM 纯正弦波逆变技术,将飞机115/200V/400 Hz电源变换成交流110 V/60 Hz 和直流5V(USB 口)电源,降低了THD 并提高了转换效率。大量验证表明,该电源可靠、安全、高效,并已取得中国民航局颁发的PMA 证书。

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
