浮波開關
英文
float switch-
Now, the traditional h - bridge maglev chopper had been widely used in practice, which had much merit, such as the simple structure and reliable quality
磁懸浮列車目前使用的是傳統的h -橋硬開關斬波器，其結構簡單、性能可靠。Above all, the defects cannot obscure the virtues, this novel zvs chopper is a preferable chopper structure, which can be applied in maglev chopper broadly
然而，瑕不掩瑜，新型的零電壓軟開關仍然是一種較好的斬波器拓撲結構，在磁懸浮列車斬波器的應用上有著廣泛的前景。Become a kind of new electronics circuit - current - mode circuit. it is replacing the traditional design method of the voltage - mode in the high frequency high - speed signal processing realm 。 this thesis mainly discussed the modified second - generation current conveyors based on the current - mode kinds of new cuicuit components, they are stronger modified standard current - mode parts in fuctions on this foundation. mainly including the modified differential difference current conveyor ( mddccii ) 、 the fully balanced second generation current conveyor ( fbccii ) 、 ( full balances ) four - terminal floating nullor ( fbftfn ) and the current differencing buffered amplifier ( cdba ), they are all function very strong standard current - mode parts, they all can provide some circuit functions of better than general operation amplifier, because they have the voltage importation and the current importation, therefore use it since can carry out the voltage - mode signal processing circuit expediently, can also carry out the current - mode signal processing circuit expediently, and have to increase the benefit bandwidth to accumulate more widely than the voltage - mode, but have their advantages more according to the current - mode filter of the modified current conveyor, because it constitutes in brief, the filter wave function is stronger and they are better than in general use operation amplifier of many advantages, be easy to composing for example 、 high speed 、 frequency bandwidth 、 the power supply voltage requests low 、 consume small, the impedance is different from etc. advantages, otherwise they have biggish dynamic range, and flexible circuit synthesize, so they are the best active parts
從第二代電流傳輸器ccii入手，重點研究了以下幾種改進型的第二代電流傳輸器:改進的差動差分電流傳輸器mddccii 、全平衡第二代電流傳輸器fbccii 、多輸出四端浮地零器ftfn 、全平衡四端浮地零器fbftfn 、電流差分緩沖放大器cdba的電路結構及其模型。然後在此基礎上系統地研究了基於這幾種改進型的第二代電流傳輸器的濾波器的設計方法，主要方法和結果如下:利用mddccii設計了差分式連續時間電流模式低通、帶通濾波器;電流模式跳耦結構考爾低通濾波器;利用fbccii設計了帶通二階節濾波器及電流模式雙二階通用濾波器;設計了基於多輸出端ftfn的電流模式二階通用濾波器電路;通過數字化開關選擇的基於fbftfn的電流模式通用濾波器;設計了基於最少個數電流緩沖放大器（兩個cdba ）的多功能通用電流模式濾波器及其在非理想因素情況下分析。設計濾波器的主要方法是採用級聯設計、運算模擬（信號流圖法）和反饋設計（跳耦法） 。This paper mainly designs a novel zero - voltage - soft ( zvs ) switching dc / dc chopper and validate on experiment which could be have abroad application in maglev, that is based on the study object of low and middle speed electromagnetic - suspension ( ems ) maglev
