These methods all can be used to solve the magnetic aberration hi the conventional push - pull converter 這兩種方式均可以解決傳統(tǒng)推挽直流變換器存在的偏磁問題。
Comparing with usual push - pull converter , the bias - magnetic can be retrained due to the clamping capacitance . but bias - magnetic can not be avoided 推挽正激變換器相比普通的推挽式變換器,由于箝位電容的存在,偏磁可以被抑制,但并不能完全消除。
The thesis focused on the dc link topology of the modulariation aviation static converter . first , the push - pull converter is developed . then , the principle of push - pull forward converter is analyzed in detail 本文主要針對模板化航空靜止變流器直流環(huán)節(jié)進行研究,研究了推挽、推挽正激和隔離型boost三種電路方案。
Using the modified method , 6 kinds of tl topologies of single - switch converter are obtained . the deep research reveals that these tl topologies can have less value of the inductor by using interleaving modulation strategy compared with conventional modulation strategy on the condition that the current ripple of the inductor are the same . some drawbacks such as high voltage stress , difficulty of realizing soft - switching , and magnetic aberration were presented in the conventional push - pull converter 對基本方法進行改進,提出了適合6種單管直流變換器的三電平拓撲變換方法,成功地得到了其三電平拓撲,開關(guān)管的電壓應(yīng)力降為原來的一半;經(jīng)過對這些三電平拓撲控制策略的深入研究,詳細論述了交錯開關(guān)方式可以最大幅度地減小電感的電流脈動,從而可以在電流脈動要求相同的情況下減小電感的設(shè)計值。
