摘要

本文研究了时间谐波对输出电压的影响。代替完整的分析,当交流发电机向逆变器供电时,考虑在示波器上记录的线路电流波形。当五次谐波和七次谐波的磁动势与磁场激励相反时,气隙感应最小。对于一个典型的循环逆变器负载,由时间谐波引起的气隙感应基波幅度的减小被发现为15%至20%的顺序。

Influence of Inverter Loads on the Airgap Flux of Aerospace Homopolar Alternators
In this paper the effects of the time harmonics on the output voltage are investigated. Instead of a complete analysis, the waveshape of the line current is considered as recorded on an oscilloscope when the alternator supplies an inverter. The minimum airgap induction occurs when the magnetomotive forces of the fifth and seventh time harmonic oppose the field excitation. The reduction in the amplitude of the fundamental of the airgap induction caused by the time harmonics was found to be of the order of fifteen to twenty percent for a typical cyclo-inverter load.
