Voltage limitative range
電壓限制范圍In the second place, based on the asu of buggenum igcc plant in netherlands, both static and dynamical model for distillation tower of the asu are created and some valuable conclusions are gained as well. finally, a compartmental simplified model is created for distillation tower of the asu, in order to reduce the simulation time and increase the simulation efficiency. the new model will be helpful to the further simulation and on - line optimal control for the asu of the igcc plant
其次,本文以荷蘭buggenum電站的空分系統為原型,基於matlab建立了空分系統精餾塔的半圖形化動、靜態數學模型,並通過模擬,得出了一些有價值的結論:當空分系統的壓力變化時,氧氣產品濃度的響應時間常數為兩小時左右,說明空分系統是igcc電站最大延遲環節;而且雖然氧氣濃度最後會穩定在igcc電站所要求的范圍之內,但在過渡過程中會超出限制,這些都為igcc電站的安全運行及控制系統設計提供了有價值的信息。Jedec ? an input voltage in a region of relatively low differential resistance that serves to limit the voltage swing
用於限制輸入電壓擺幅的相對低的不同阻抗范圍的輸入電壓。Under the result of the inverter ' s steady sate study, the limitation limited by two factors : the minimum time of opposing voltage and the ajustive range of power factor can be gained. a qualitative analysis method based on energy decomposing is applied to study the initialized energy
在討論串並聯逆變器穩態工況的基礎上,從最小反壓時間和功率因數調節范圍兩個限制條件,求出允許的穩態運行極限負載,啟動電路在此極限負載下能可靠地啟動就足夠了,追求更高的啟動能力沒有實際意義。You cannot switch thebutton to the faster level directly from the stop status to keep the voltage jump within usb limits ( 500ma ) during motor start up
為了保證吸塵器電機啟動時電壓波動在usb介面限制的范圍( 500毫安)內,不能直接將開關從停止位置打到快速檔。The chip is mainly applied to the portable electronic products with the following features : 2. 7v to 5. 5v input voltage range ; the 1mhz fixed frequency ; - 40 to + 85 operating temperature ; two digital inputs control on / off and select amongst three levels of brightness ; thermal shutdown and under voltage shutdown protection, low 0. 1 a shutdown current ; soft - start limits inrush current
該晶元主要應用於便攜式電子產品,其輸入電壓范圍為2 . 7 5 . 5v ,工作頻率為固定的1mhz ,可大幅度降低輸入紋波和emi輻射,工作溫度范圍為- 40 + 85 ,可使用外部使能控制信號調節led亮度及控制晶元關斷與否,具有過溫保護和輸入欠壓關斷保護功能,完全關斷模式下關斷電流可低至0 . 1 a ,具有軟啟動功能以限制啟動時的浪涌電流。For the former has inductance winding and ferromagnetic material, its measurement range is restricted by saturation, so it has a narrower range of frequency. being an inductance, it has the possibility of resonance
由於電磁式電壓互感器帶有電感線圈和磁性材料,測量范圍受鐵心磁飽和的限制,傳輸頻帶不夠寬;作為感性元件,存在鐵磁諧振的可能,可靠性差。The principles and characteristics of synchronous rectification ( sr ) are given, and advantages of self - driven sr in low power applications is detailed. review of several topologies which incorporate self - driven sr makes the constrains of conventional self - driven sr scheme apparent and thus a new scheme to drive srs is proposed. the developed single - winding self - driven synchronous rectification ( swsdsr ) scheme works properly in topologies that drive symmetrically the transformer ( push - pull, half bridge, . . ). it allows for maintaining the srs on even when the voltage in the transformer is zero, which is impossible to do in traditional self - driven approaches
本文針對低壓/大電流輸出的小功率dc / dc變換器,圍繞著變換器的效率問題,分析了同步整流的原理和特點,重點闡述了自驅動同步整流在低功率場合的優勢,在分析比較了多種與自驅動同步整流相結合使用的電路拓撲后,指出常規的自驅動同步整流方案限制了與之結合使用的電路拓撲的范圍這一局限性,從而給出了一種新穎的單繞組自驅動同步整流方案。But if we use chaotic phenomenon directly, three disadvantages exist : ( 1 ) the applied range was limited by dynamic character of the dc / dc converter system ; ( 2 ) high current fluctuation is found, and it is hard to be controlled ; ( 3 ) high output voltage fluctuation
但是利用dc / dc變換器系統本身的混沌現象來提高電路的電磁兼容性,存在著三個方面的不足: ( 1 )應用范圍受到系統本身動力學性質的限制; ( 2 )電路中的電流波動大,難以控制; ( 3 )輸出電壓波動大。Among them, phase shifted ( ps ) full bridge ( fb ) zero - voltage - switched ( zvs ) pulse - width - modulated ( pwm ) dc / dc converter has strong competitive power in big power capacity fields. but it has some limitations such as smaller load range with zvs and larger circulation energy. the ps - fb - zvs - pwm dc / dc converter with a saturable inductor utilizes saturable inductor s critical saturable current characteristic and storage energy, to enlarge load range with zvs and improve output efficiency under light load
