例句與造句

1. These devices usually consist of a rectifier stage ( producing direct current ) which is then inverted to produce AC of the desired frequency.
2. This type of use may be harmful to the rectifier stage, however, as it will only use half of diodes in the rectifier for the full load.
3. Because an AC waveform has a voltage peak that is higher than the average value produced by the rectifier, the same set operating on the same root mean square AC supply voltage would have a higher effective voltage after the rectifier stage.
4. The inverter stage converts DC, whether directly from the input or from the rectifier stage described above, to AC by running it through a power oscillator, whose output transformer is very small with few windings at a frequency of tens or hundreds of kilohertz.
5. It's difficult to find rectifier stage in a sentence. 用rectifier stage造句挺難的
