Therefore it can be seen that it will "smooth" the "twice mains frequency DC" into a near constant DC voltage.
因此它可以把“两倍于电源频率的直流电”进行“平滑化处理”，成为一个接近恒定的直流电。
This kind of material is already extensive now to be used for common mode choke of high frequency circuit changer, high frequency dc-to-ac converter, zero order mutual-inductor and etc.
这种材料现已广泛用于共模扼流圈、高频开关电源、高频逆变器、零序互感器等许多电器元件。
