推荐了一种新型的输入滤波器结构，它只用两个扼流圈铁心，并使尺寸减小。
A new input filter topology is proposed, using only two choke cores and providing the size reduction.
旨在提供一个大电流电源供应商一般采用扼流圈输入滤波器，如图8 - 7。
Power suppliers designed to deliver a large current generally use a choke input filter, Figure 8-7.
高频扼流圈是一段未闭合的铜，和其终端等效的边缘电容形成一个低通滤波器，可以有效地滤除馈入信号中的高频成分。
It acts as the LPF, effectively eliminating the high frequency component in the feed-in signal. The groove in the central region working as a loading capacitance in the open end is also discussed.
