摘　　要：介绍了航空交流发电机及其调压电路,阐述了调压基本原理,分析了基于集成运放的调压电路工作过程。对决定调压性能的电压检测和反馈控制两个关键技术进行改进,提出了采用RMS-DC专用转换芯片AD536A进行电压真有效值(True RMS)检测电路设计,以提高电压检测的精度。同时采用包括发电机电压、励磁电流、负载电流和发电机频率四个反馈参量的多环反馈调压技术,提高发电机的动态调压性能。This article introduced aircraft AC generator and voltage regulation circuit , and elaborated the basic princi- ple of the voltage regulator, and analyzed the working principle of regulation circuit based on integrated operational ampli- fier. The key technologies including voltage detection and feedback controlling are improved, which finally affected the per- formance of voltage regulation. The RMS^DC special converter AD536A is used for the voltage true Root-Mean-Square de- tection, which can improve the precision of voltage detection. And the multi-loop feedback voltage controlling technology is used, which has four parameters including generator voltage, magnetic field exciting current, load current and generator frequency, to improve the dynamic voltage regulator performance of AC generator.
