本廠能為廣大用戶(hù)設(shè)計(jì)各種不同輸入電壓及頻率的充電設(shè)備，請(qǐng)?jiān)谟嗀洉r(shí)注明輸入電壓及輸入頻率。 - The frequency - centered sla theory claims that input frequency is an essential factor affecting l2 acquisition order and determining the productability of language constructions
摘要以頻率為中心的二語(yǔ)習(xí)得理論認(rèn)為，輸入頻率是影響第二語(yǔ)言習(xí)得順序的重要因素，并對(duì)語(yǔ)言結(jié)構(gòu)的能產(chǎn)性起著決定作用。 - The characteristics of three - level ( tl ) converter and its effect to the zero - crossing distortion are analyzed , and extended it to ml converters , which are suitable for the high input frequency pfc application
文章詳細(xì)分析了三電平( three - level , tl )變換器的特點(diǎn)和對(duì)輸入電流過(guò)零畸變的改善作用,并推廣至多電平變換器。 - The slope signal analyses and sinusoidal signal analyses show that the dnl 1 / 2lsb , at 49 . 902 mhz input frequency and 100mhz sampling frequency , sfdr is 75 . 5db and the or output can detect correctly whether the input signal is overflow and the system has good linearity
輸入頻率為49 . 902mhz的滿幅( 500mv )正弦信號(hào),測(cè)得adc的無(wú)雜散動(dòng)態(tài)范圍( sfdr )為75 . 5db ,系統(tǒng)的具有良好的線性度。 - It's difficult to find input frequency in a sentence. 用input frequency造句挺難的
- However input current distortion at the zero - crossing of the input voltage is a common problem in active pfc converters , and it becomes more serious as the line frequency is increased . the purpose of this thesis is to reduce the zero - crossing distortion of input current at high input frequency application
但有源pfc變換器存在輸入電流過(guò)零畸變的缺陷,并且隨著輸入頻率的升高而越來(lái)越嚴(yán)重,本文的工作就是針對(duì)解決高輸入頻率下嚴(yán)重的輸入電流過(guò)零畸變而展開(kāi)的。 - The features of this equipments include multi - channel acquisition ( 16 paths ) , high precision ( 0 . 2 level ) , wide input frequency ( 25 - 20 khz ) and strong anti - interference capability . through the tests at several substations we found the on - site operation of picep is good for electrical measurements , r & d and technical development . it is accepted and used widely
Picep具有采集通道多（ 16路） 、精度高（ 0 . 2級(jí)） 、輸入頻率寬（ 25 - 20khz ）及抗干擾能力強(qiáng)等特點(diǎn)，經(jīng)多個(gè)變電站、不同狀態(tài)的實(shí)際試驗(yàn)，證明現(xiàn)場(chǎng)使用效果良好，性能指標(biāo)完全滿足了設(shè)計(jì)要求。 - 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(dāng)交-交變頻器的輸入頻率非常高，通常為20khz時(shí)，為了在零電壓條件下實(shí)現(xiàn)逆變器開(kāi)關(guān)管的通斷，變換器的開(kāi)關(guān)時(shí)刻必須選擇在高頻交流電壓脈沖為零時(shí)，這意味著變換器開(kāi)關(guān)時(shí)刻在時(shí)間軸上成為不連續(xù)的點(diǎn)，而常規(guī)的硬開(kāi)關(guān)pwm變換器是將開(kāi)關(guān)時(shí)刻選擇在任意時(shí)刻。 - With each other the lose the true intermodulation distortion department to point to be lost by enlarger a kind of importation signal for into of with and badly really . for example , at input frequency to enlarger to 1 the khz with 5 khzs admixture signal empress , would then produce 6 khz 1 khz with 5 khz it with and 4 khz 1 khz with 5 khz it bad of with each other the lose the true composition
互調(diào)失真intermodulation distortion系指由放大器所引入的一種輸入信號(hào)的和及差的失真。例如，在給放大器輸入頻率為1khz和5khz的混合信號(hào)后，便會(huì)產(chǎn)生6khz 1khz和5khz之和及4khz 1khz和5khz之差的互調(diào)失真成份。
