事實(shí)上,當(dāng)電流環(huán)路的穿越頻率小于開(kāi)關(guān)頻率的一半時(shí),它的control-to-output傳輸函數(shù)可以被精確表述.

..... 當(dāng)電流環(huán)路閉合于比一半開(kāi)關(guān)頻率小的頻率時(shí) (?) ,.......

這個(gè)最好是看上下文翻,不知道文章中是不是說(shuō)有兩個(gè)控制回路在里面切換.如果有的話,那應(yīng)該這樣翻:“事實(shí)上,當(dāng)電流回路閉合頻率小于二分之一開(kāi)關(guān)頻率時(shí),控制到輸出的傳函可以被精確描述.”

In fact, the control-to-output transfer function can be accurately described with its current loop closed at frequencies less than half of the switching frequency.
事實(shí)上,當(dāng)頻率小于開(kāi)關(guān)頻率1/2時(shí),控制-輸出的傳遞函數(shù)可以用閉環(huán)電流回路來(lái)描述.
