Development and digital control of inverter systems with galvanic isolation and front-end SMR
碩士 === 國立清華大學 === 電機工程學系 === 96 === 本論文旨在研製具切換式整流器前級及電氣隔離之變頻器系統並從事其數位控制。首先,建立具低頻輸出隔離變壓器與高頻變壓器隔離直流鏈之單相變頻器,並比較評估其操控性能。後者以具高頻隔離變壓器之全橋式直流/直流轉換器提供變頻器之直流鏈電壓。為達到零電壓軟式切換,本文採用負載串聯諧振軟式切換。於控制方面,藉由強健波形控制法則,達到在線性與非線性負載下皆能具有良好穩態及動態之瞬間波形追控,對於隔離型全橋式直流/直流轉換器,亦提供適當之控制器設計,以使其具有良好調節特性。 切換式整流器亦稱功因校正整流器,因可提供具良好調控之直流鏈電壓及交...
