Abstract

In the modern airport system, safety for airport to take off and landing is an important matter. Navigational lighting aids are necessities for it. Accurate and constant current should be provided for lighting aid. This paper researched two kinds of topological structures and some control strategies. AC-AC converter and AC-DC-AC converter are proposed, both of them can provide accurate constant current for lighting aid. It can be distinguished from power supply. Three-phase source supplied for AC-DC-AC converter and Single-phase-source supplied for AC-AC converter. Topology of AC-DC-AC converter has lager power than AC-AC converter, then MATLAB/SIMULINK was used to simulate the two kinds of typologies with two kinds of control strategies named current single loop control strategy and voltage current double loop control strategy, the result showed that AC-DC-AC converter had faster response speed and more accurate output current than AC-AC converter. Voltage current double loop control strategy used in AC-DC-AC converter had more advantages than AC-AC converter.

两种拓扑结构恒流调节器的性能研究

在现代机场系统中，机场起降安全是一件重要的事情。助航照明设备是它的必需品。应提供准确和恒定的电流以辅助照明。本文研究了两种拓扑结构及其控制策略。提出了交流-交流变换器和交流-直流-交流变换器，它们都能提供精确的恒流辅助照明。它可以与电源区分开来。交-直-交变换器采用三相电源，交-交变换器采用单相电源。AC-DC-AC变换器的拓扑结构比AC-AC变换器具有更大的功率，然后利用MATLAB/SIMULINK对两种类型的电流单环控制策略和电压电流双环控制策略进行仿真，结果表明AC-DC-AC变换器比AC-AC变换器具有更快的响应速度和更精确的输出电流。交流-直流-交流变换器采用电压电流双环控制策略比交流-交流变换器具有更多的优点。
