href="http://www.ex-cimer.com/news/listbylabel/label/靜止變流器"><em>靜止變流器</em></a>的效率一般不超過80%。為實現(xiàn)<a class="contentlabel" href="http://www.ex-cimer.com/news/listbylabel/label/靜止變流器"><em>靜止變流器</em></a>的模板化和高效率，提出了級聯(lián)型航空靜止變流器方案，由四臺逆變橋的輸出級聯(lián)得到系統(tǒng)輸出，對應(yīng)由四臺高頻直流變換器提供四臺逆變橋所需要的隔離直流電源。由于級聯(lián)逆變器采用低壓功率場效應(yīng)管和低開關(guān)頻率，具有很高的效率，因此新型航空靜止變流器的效率主要取決于直流變換環(huán)節(jié)。<br

">　　1kVA新型航空靜止變流器的直流環(huán)節(jié)的設(shè)計功率為300W，輸入為18—32V，輸出為48V，輸入電壓低、電流大。在輸入低壓大電流應(yīng)用場合，推挽電路和單端正激電路是兩種可選方案。但推挽電路存在變壓器鐵芯偏磁、開關(guān)管關(guān)斷時漏感能量在開關(guān)管上引起高的電壓尖峰等問題。正激電路變壓器為單向磁化，磁芯利用率低，同時還需要附加去磁電路，使電路變得復(fù)雜。一種新的電路拓?fù)洹仆煺る娐?，集中了正激電路和推挽電路的優(yōu)點，同時克服了二種電路的缺點，具有：a）抑制變壓器的鐵芯偏磁；b）變壓器磁芯雙向磁化；c）抑制開關(guān)管兩端的關(guān)斷電壓尖峰等優(yōu)點，是新型航空靜止變流器直流環(huán)節(jié)的優(yōu)選電路方案。<br
