臨界載荷電流-
In order to eliminate the influence of the output filter capacitor current on the grid current, a novel control strategy for the grid - connected inverter in grid - tied and off - grid modes is proposed. the control strategy can also realize seamless transfer between grid - tied and off - gird modes. the grid - connected inverter can supply power to the critical load when the grid is off
本文針對傳統並網控制策略進網電流受輸出濾波電容電流影響的問題，提出了一種新的並網控制策略，該控制策略能基本消除輸出濾波電容對進網電流的影響，實現獨立與並網兩模式之間的無縫切換，對關鍵負載起不間斷供電的作用。 -
The equilibrium current in 24 - pulse traction rectifier system is analyzed. the relation between critical load and resistance of traction rectifier transformer is discussed
摘要分析了24脈波牽引整流系統中的均衡電流，討論了臨界負載與牽引整流變壓器阻抗參數的關系。 -
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
其中，移相控制零電壓開關脈寬調制dc / dc全橋變換器在大容量領域很有競爭力，但它具有實現零電壓開關負載范圍小，循環能量大等限制，帶飽和電感的移相控制零電壓開關全橋變換器利用飽和電感的臨界飽和電流特性及儲能，來擴大零電壓開關（ zvs ）的負載范圍，提高輕載時的輸出效率，具有非常重要的研究價值。 -
On the basis of the test about air conditioner, its load characteristics are analyzed, including the static characteristics, drop out characteristics, starting characteristics and its responses to voltage dips. it shows that the current impact can reach five to eight multiples when the air conditioner started and come back within 0. 3 to 0. 5 second. 0. 6 pu voltage is the critical voltage whether the air conditioner will stall
分析發現，空調啟動時電流沖擊倍數可達5 8倍，在0 . 3 0 . 5秒之內平息； 0 . 6u _ n為空調停機的臨界電壓，因此空調的電壓擾動特性可以分為兩種情況：一為較小擾動情況下空調尚未停機時的動態；另一為大擾動導致空調停機時的動態。
