針對地磁的影響情況，介紹了實際採用的糾正彩色顯像管著屏偏差的具體方法和途徑。With the best modulation strategy which was found on condition that it must have largest energy transfer ratio, smallest current ripple of the inductor, and realizing zvs of each switches, the converter overcomes the drawbacks presented by the conventional zvs fb converter, such as high voltage stress of each switches, large current ripple of the inductor, and severe parasitic ringing on the rectifier diodes, so it can get higher efficiency, faster respond speed, and wider application area. the operation principle of the proposed converter is analyzed and verified by a 3kw, 50khz experimental prototype. experiments and research results show that the scheme of the tl topology derivation is reasonable, adjusted modulation strategy makes some other severe problems in conventional topologies easy to solve or makes the converter more competitive
研究結果表明，本文提出的三電平拓撲變換方案合理，針對各種三電平拓撲尋找到的控制策略可以解決變換器存在的某些問題或使變換器表現出更突出的優勢：例如針對單管直流變換器三電平拓撲的控制策略可以減小電感的設計值，針對推挽直流變換器三電平拓撲的控制策略可以實現開關管的軟開關、解決變壓器偏磁問題等，針對全橋直流變換器三電平拓撲的控制策略可以減小電感的設計值、實現開關管的軟開關等。Solar wind flows out from the corona the sun s outer atmosphere into interplanetary space at speed of between 300 and 900 km per second. it causes fluctuation to the earth s magnetic field, which we call magnetic storm. such event will cause deflection of compass needles
而太陽風則以每秒300至900千米的速度由日冕太陽外大氣層向外拋射，進入行星際空間，對地球磁場造成擾動而產生磁暴，導致指南針指針偏移，嚴重的話更會導致電力受阻和電話線路中斷。This paper describes the study of an original radial - axial mb biased with permanent magnet, including its operation principle, mathematic model, the design of the structure, and so on. a method of design and checkout of the mb is put forward
