整流发电机 meaning in Chinese

commutator generator

Because central potentials of four y windings in 12 - phase generator are not equal each other and there is no common reference inside the generator , it is difficult to identify the on / off of rectifying elements . in this paper , by using a mathematical model with line voltage substitute for phase voltage , the problem that there is no common reference in the 12 - phase generator with rectifier is solved . based on results of the studies on small prototype , 920kw charging generator applied in a submarine is improved in design , and therefore power oscillation with high magnitude when two generators are operating in parallel
由于十二相发电机中四个y绕组的中点电位不等，电机内部没有公共参考点，从而在判断整流元件导通时，不能象三相同步发电机整流系统那样认为阳极电位最高或阴极电位最低的整流元件导通，本文采用了以线电压代替相电压建立十二相整流发电机的数学模型，从而解决了十二相发电机无公共参考点的问题。
