As early as the end of 19th century, people had discovered the distortion problem of voltage and current existing in the distribution system when the alternating current arisen as a newly motive form.
早在19世纪末,当交流电以一种新兴的动力形式出现时,人们就发现了系统中电压、电流存在畸变的问题。

A rectifier converts the power from alternating to direct form, a regulator ensures that the output voltage is properly matched to the battery voltage as engine speed varies.
