With the development of electronic technology in the field of high - frequency and high - power, power mosfet is gradually enhancing its important status in semiconductor apparatus and is being widely applied in power converters as switch. with the increasing of the operating frequency ( > 200khz ), the energy loss caused by parasitic capacitance will affect the efficiency of power transforming in converters. especially in the applications of high frequency power supply using mosfet as main devices ( the unit of frequency is mhz ), the energy loss caused by the switch process will badly affect its efficiency
隨著電力電子技術進一步向高頻的大功率用電領域發展，功率mosfet在各種電力半導體器件中的重要地位日益顯著，使用功率mosfet作為開關器件的功率轉換電路也日益增多，但隨著器件開關頻率的提高（大於200khz ） ，由器件極間電容引起的能量損耗將會影響到功率轉換電路的能量傳輸效率，特別是在以mosfet作為開關器件的高頻感應加熱電源中（工作頻率可達兆赫） ， mosfet在開關過程中的能量損耗嚴重影響到電源的效率，因此如何減小開關器件的損耗提高高頻功率轉換線路的效率成為電力電子技術領域的重要研究課題之一。 -
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。 -
The parasitic thermal energy produced combined with the electricity that is generated make the treatment plants self - sufficient and wastewater from sewage treatment works can be purified to industrial water quality for reuse as irrigation water or can be treated to even higher quality standards if required
產生的熱量與生成的電能相結合使處理工廠可以自給自足，廢水通過污水處理系統凈化后可以達到工業用水質量並做為灌溉水重新使用，或者處理為符合更高質量標準的用水（如果需要） 。
