对AVR403型电压调节器的分析

Analysis of the Voltage Regulator AVR403

当同步发电机输出电流大小与功率因数改变时,其电枢反应与内阻抗压降将改变,则发电机输出电压也将改变。为使发电机输出电压保持额定值,通常都有自动电压调节器与发电机配套工作。本文较详细地分析了MD-80飞机使用的AVR403型电压调节器各部分电路的工作原理,以及整机调压的工作过程,并阐述了该调压器的特点。

When the output current and power factor of a synchronous generator vary,there will be a chance in both the voltage drop of the in- ternal impedance and armature reaction,and the output voltage of the ge- nerator,To maintain the rated value of the generator output voltage,the- re is often an automatic voltage regulator co-operating with the generator. This paper analyses the principles of the circuits and working proces- ses of the AVR403 regulator used in the MD-80 aircraft,and describes its characteristics.
