The first-part of this paper evaluates the main stability theories concerned and concludes the conceptualization steps and essentials covering the various methods. Different disturbed-measure functions are studied in terms of their formulations and characteristics. Both Lyapunov functions and TEFs can be constructed only in a heuristic way of case-by-case. Ignoring changes in the disturbed-measure function's value after clearing the fault, Lyapunov functions and TEFs are applicable to neither nonautonomous one-machine infinite-bus systems nor any multimachine systems. Moreover, TEFs cannot guarantee the sign of errors because they don't satisfy the conditions for Lyapunov functions.

作為第1篇，文中歸納出這3種方法的共同分析步驟和要素女生小穴自慰网站，并比較各種受擾程度函數(shù)丝袜日韩无码激情视频，指出：李雅普諾夫函數(shù)和TEF的建立都必須從具體模型出發(fā)并只能依靠啟發(fā)的方式，它們沒有考慮受擾程度函數(shù)的值在故障清除后的變化最新男女一级性爱视频在线，因此既不適用于復雜模型的單機系統(tǒng)日韩网友自拍区在线观看视频网站大全，也不適用于任何多機系統(tǒng)；又由于這2種方法都基于很強的假設九一高潮视频国产在线，故分析的誤差可能非常大手机看A片小视频，而TEF法更是由于不滿足李雅普諾夫函數(shù)的條件而可能得到冒進的結果。

Some circuits use resonant, quasi-resonant, and/or multi-resonant techniques. However, voltage or current stresses in these converters are higher and require the devices of higher VA rating. Some circuits use passive snubbers or active clamp techniques. However these converters become more complicate. Phase-shift ZVS technique has been used in bidirectional DC/DC converters since it can realize ZVS for all switches without auxiliary switches.
