摘要
随着现代电力电子技术的进步,航空动力系统出现了多电化、全电化的概念。在多电发动机中,主要次级功率以电的形式进行传递和控制。发动机复杂的工作环境和多变的工作状态往往导致发电电压不稳定甚至出现很大的波动,需要设计安全可靠、高效的DC/DC变换器进行电压的转换,为发动机稳定工作以及飞行的安全提供保障。DC/DC变换器是连接直流输入电压与负载之间的纽带,其性能的优劣取决于拓扑硬件电路以及控制算法的设计。本文主要讨论多电发动机DC/DC变换器控制的国内外研究现状以及基本原理和控制技术。
With the progress of modern power electronic technology, the concept of moreelectric and full-electric has been appeared in aerospace power system. In more-electric gas turbine engines, main secondary power is transmitted and controlled by electricity. Because of the complicated work environment and complex operating state of gas turbine engines, the generator voltage instability or even large voltage fluctuations will appear. In order to ensure steady work of engines and flight security of aircrafts, safe and reliable DC/DC converter needs to be designed. DC/DC converter is the bond connecting input DC voltage and load, its performance depends on design of hardware topology circuit and control algorithm. This article mainly focuses on research situation at home and abroad of DC/DC converter and its fundamentals and control technology.
