在532nm的調(diào)q脈沖激發(fā)光和不同波長(zhǎng)的連續(xù)探測(cè)光作用下，分析和研究了野生型的細(xì)菌視紫紅質(zhì)( wt3 )膜的光循環(huán)過程中的快速響應(yīng)特性及各中間態(tài)的快速光吸收特性，得到了微秒級(jí)的快速光開關(guān)結(jié)果。 - Multilevel inverter technology is a pop research in high voltage and high - power converting fields . it can synthesize multilevel output with the distribution of dc voltage and the combination of different switching actions to reduce voltage stress across the switches and bulk of the equipment , and lessen output harmonic distortion and switching loss of the inverter
多電平逆變器是當(dāng)前高壓大功率電能變換領(lǐng)域中的研究熱點(diǎn)之一,它通過對(duì)直流側(cè)的分壓和開關(guān)動(dòng)作的不同組合,實(shí)現(xiàn)多電平階梯波輸出電壓,能有效地減小器件承受的電壓應(yīng)力,縮小裝置體積,減小輸出電壓諧波和開關(guān)損耗。 - 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)逆變器開關(guān)管的通斷，變換器的開關(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)的硬開關(guān)pwm變換器是將開關(guān)時(shí)刻選擇在任意時(shí)刻。 - Although dm can also solve the modulation time error , but the output waveforms can ’ t reach the industrial standard ( total harmonic distortion thd ) . considering this , a new control strategy called current optimal control ( coc ) is presented in paper . coc is that system samples the output value real time , comparing with expected value , considering all switching actions available then draw a concluding to decide which way would be fastest and best way to render system smooth
針對(duì)這一缺點(diǎn),本文提出了一種更好的控制策略,電流最優(yōu)delta調(diào)制,它是在電流滯環(huán)控制的基礎(chǔ)上,根據(jù)電路的輸出信號(hào)來分析,考慮所有可能的逆變器動(dòng)作來決定選用哪一種開關(guān)轉(zhuǎn)換方式能最快最平穩(wěn)地達(dá)到預(yù)期值,采用的是一種電流預(yù)測(cè)控制手段,從而使輸出波形的紋波最小。 - Continuous - time filter needn ’ t a / d switch , data processing , d / a switch technique and so on to finish filtering function with analog signal like digital filter . and it needn ’ t switch action to sample data in the discrete time with analog signal like switched capacitor filter . so continuous - time filter has several advantages , such as high processing speed , simple circuit configuration , and low power consumption
對(duì)每種方法都進(jìn)行了詳細(xì)的推導(dǎo),總結(jié)了每種設(shè)計(jì)方法的設(shè)計(jì)步驟、適用場(chǎng)合,舉例用每種設(shè)計(jì)方法對(duì)具體濾波器進(jìn)行了電路設(shè)計(jì)、靈敏度特性分析、失真特性分析等,并用計(jì)算機(jī)仿真驗(yàn)證了電路方案。 - It's difficult to find switching action in a sentence. 用switching action造句挺難的
