求翻译：对电量进行开关周期平均运算后，将保留原信号的低频部分，而滤除开关频率分量、开关频率谐波与其边频分量。是什么意思？

A switching cycle of the average computing power, it will keep the low-frequency part of the original signal, and filter out the switching frequency components, while the switching frequency and its harmonic frequency components.

Electricity sales to the switching cycle average computing, will retain the original signal frequency switching frequency filtering, and part weight and switching frequency harmonic frequency weight with its side.

Will carry on the switch cycle average calculating operation after the electric quantity, will retain the original signal the low frequency part, if but will filter the turn-on frequency component, the turn-on frequency overtone the side frequency component.

To switch the power cycle the average after the operation, will retain the low frequency portion of the original signal, and switching frequency harmonic filter switching frequency component with frequency components.

A switching cycle of the average computing power, it will keep the low-frequency part of the original signal, and filter out the switching frequency components, while the switching frequency and its harmonic frequency components.
