The switching function model may be divided into two models of high frequency and low frequency. Then the average model for condition space of the rectifier is developed.

通过对开关函数求傅里叶级数，将开关函数模型分解为高频和低频两个模型，从而求得整流器的状态空间平均模型。

"Also, after five years, we'll return the land back to its owners in exactly the same condition as we got it, and then the community can decide if it wants a more permanent retail space there, " he says.
