low voltage complex 中文意思是什麼
low voltage complex
解釋
低電壓綜合波,低電壓復合波-
In this paper global joint planning for middle and low voltage network is considered. both line arrangement and cross section and transformer arrangement and rate are considered. it is a non - line combined optimum problem more complex than single network planning
本文從整體的角度考慮中壓和低壓配電網路的聯合規劃，不僅考慮了線路走向和導線截面大小，而且考慮了變壓器的布置位置和容量，這是一個比單純的網架規劃更復雜的非線性組合優化問題。 -
The vertical structure optimization through simulation of the new structure, low loss igbt ( lpl - igbt ) has been discussed in detail in this paper. in comparison with the prevalent igbt, lpl - igbt has not only the merit of transparent back emitter and high lifetime of carriers owned by npt - igbt but also the complex n7n + voltage sustain layer structure owned by pt - igbt. not only possesses lpl - igbt lower power loss but also the other capacities are no better than npt - igbt such as break down voltage, current capacities, safe operation area and cost
與現有igbt相比較， lpl - igbt在結構上保留了npt - igbt中的透明發射區和高載流子壽命的本質優點，同時又具有pt - igbt中n ~ - n ~ +復合薄耐壓層的優點；在器件性能上， lpl - igbt不僅具有比npt - igbt更低的能量損耗（包括通態損耗和開關損耗） ，而且其餘性能如器件耐壓、電流密度、安全工作區以及製造成本等相對現有npt - igbt均有明顯改善。
