switching action 中文意思是什麼
switching action
解釋
開關作用-
High - frequency link power converters are receiving increasing attention. when the input frequency of ac - ac converter is quite high, such as 20khz or above, in order to make sure the converter switching action is restricted to the zero crossing point of the link voltage, the switching cycle becomes discrete pulse spectrums, however, the conventional pwm converters are ruled out because they would fail either to the efficiency or the low - distortion criteria
當交-交變頻器的輸入頻率非常高，通常為20khz時，為了在零電壓條件下實現逆變器開關管的通斷，變換器的開關時刻必須選擇在高頻交流電壓脈沖為零時，這意味著變換器開關時刻在時間軸上成為不連續的點，而常規的硬開關pwm變換器是將開關時刻選擇在任意時刻。 -
In a remote communication system, the action taken by a control station whereby messages addressed to an inoperative station are accepted and stored at the control station until they can be sent to the destination station. the control station may be a computer in a message switching system
在遠程通信系統中，當報文發往的工作站處于不工作狀態時控制站所採取的行動，即接收並存儲該報文直到該工作站恢復工作時，再由控制站將報文送給它。在報文交換系統中，控制站可以是一臺計算機。 -
