1.[问]汽车用交流发电机与直流发电机主要有哪些区别? [答]为了满足汽车拖拉机上蓄电池充电的需要,所以汽车拖拉机上只能采用直流供电。所谓半导体交流发电机,就是在它的内部装上了一组硅整流元件,使交流发电机发出的交流电变成直流电,就象直流发电机中电流通过换向器(又叫整流子)时将电流整流变成直流电一样。不过,一个是用硅整流元件整流,另一个是用换向器整流。在结
1. [Q] What are the main differences between automotive alternators and DC generators? [A] In order to meet the needs of battery charging on automobile tractors, DC tractors can only be powered by DC power. The so-called semiconductor alternator, is in its interior with a set of silicon rectifier components, so that the AC alternator into DC power, just as DC current through the commutator (also called commutator) will Current rectification becomes the same as direct current. However, one is rectified with a silicon rectifying element and the other is commutated with a commutator. At the end
