Four typical actively clamped resonant dc - link inverter ( acrdcli ) applications - - - - - - full - bridge voltage source inverter ( vsi ) , half - bridge vsi , full - bridge current source inverter , as well as three - phase vsi , are selected as models 論文分別以全橋、半橋、電流型以及三相拓撲結構為范例進行雙幅諧振直流環節技術研究。
In order to expand the application of the two - amplitude actively clamped resonant dc - link technology to half - bridge inverter , half - bridge two - amplitude actively clamped resonant dc - link inverter ( hbtacrli ) and the corresponding control strategy are proposed 為了擴展雙幅有源箝位諧振直流環節技術在半橋電路中的應用,本文提出了半橋雙幅有源箝位諧振直流環節逆變器( hbtacrli )及其控制。
The two - amplitude resonant dc - link technique offers a good solution to the " bottleneck " problem of the traditional actively clamped resonant dc - link , that is , the high operation current and losses on the resonant loop . by this way , the resonant dc - link technique can be widely used in higher power application 雙幅諧振直流環節技術解決了傳統有源箝位諧振直流環節中諧振回路的電流和損耗過大這一“瓶頸”問題,拓寬了諧振直流環節技術在大功率場合的應用。
