摘要

全桥整流器对交流发电机输出的有害影响值得海军界关注。在发电机定子处观察到的谐波不仅会产生磁滞和涡流损耗，还会产生影响发电机寿命的电压尖峰。影响寿命的两个主要因素是谐波和电压尖峰引起的局部加热，这些因素会通过局部放电导致绝缘失效。感应涡流与频率平方成正比。

Generator Life and Power Electronics

The deleterious effect of full bridge rectifiers on the output of an AC generator deserves attention from the Naval community. The harmonics observed at the stator of the generator not only introduce hysteresis and eddy current losses, but voltage spikes that impact the life of the generator. The two primary factors compromising life are localized heating due to harmonics and voltage spikes that cause insulation failure through partial discharge. Induced eddy currents are proportional to frequency squared.
