  • 例句與用法
  • For ballasts with rest mode facility changeover from rest mode to normal mode shall occur automatically at greater than 0 . 9 times the off cycle extended to 3 s and the ballast put into the rest mode after 2 s of the off periods in the 500 switching cycles
    帶有休止狀態(tài)裝置的自容式應急燈具,從休止向正常狀態(tài)的轉(zhuǎn)換應在不大于0 . 9倍額定電壓下自動運行3秒,在500次開關(guān)周期結(jié)束切斷電源的2秒時間內(nèi)應使自容式燈具進入休止狀態(tài)。
  • 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(xiàn)逆變器開關(guān)管的通斷,變換器的開關(guān)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(guān)時刻在時間軸上成為不連續(xù)的點,而常規(guī)的硬開關(guān)pwm變換器是將開關(guān)時刻選擇在任意時刻。
  • The distortion introduced by switching power amplifier is typically larger than in their linear counterparts due to intrinsic nonlineariry of switching converter . one of the key factors of affecting fidelity of switching power amplifier is control technique . one cycle control theory developed since 1990s is a large signal nonlinear pwm technology , which basic concept is to force the average of the controlled switch - variable to be equal or proportional to the control reference in each switching cycle . one cycle control technique features the merit of simple circuit structure , high control precision , fast dynamic response , and control performance not affected by the variable of power parameters . it is very suitable to control switching power amplifier
    控制技術(shù)是影響開關(guān)功率放大器保真度的關(guān)鍵因素之一。單周控制理論是20世紀90年代初提出的一種大信號、非線性pwm控制技術(shù),其基本控制思想是保證在每一個開關(guān)周期中開關(guān)變量與控制參考量相等或成比例。它具有結(jié)構(gòu)簡單、控制精度高、響應速度快,控制性能不受電源參數(shù)變化影響等優(yōu)點,因此非常適合于控制開關(guān)功率放大器。
