Stalactites are exquisitely carved, dignified and beautiful, they have many fantastic names : jade trees and agar flower ; lovers ' party ; welcome fairy ; stone flower bars ; jade fish ; supernatural being party ; pilgrimaging stone ; dragon and phoenix double candle ; goddess descending to the world ; seven fairies ; jade sky - supporting bar ; fairy shower … the wideness and highness of goddess temple are only 100 meters and 30 meters respectively, but it contains all kinds of karst sculpting in the world
宮」是地下喀斯特風光的典型代表，鐘乳石玲瓏剔透、秀美端莊，玉樹瓊花、鵲橋會、仙娥迎賓、石花寶柱、玉鱗瀉波、群仙聚會、仰仙巖、龍鳳雙燭、仙女下凡、七仙女、玉柱擎天、瑤池、神女出浴… …神女宮寬不過百米，高不過三十米，但卻峰迴路轉，移步換景，重重疊疊，融匯了世上種種喀斯特造型。A novel cycloconverter - rype three - phase hf link inverter topology for soft - switching based on phase - shifted full - bridge mode is proposed, whose main advantages are as follows : under the conditions of d < i < and overlap - d, the switches of the leading leg are turned on at zvs and the switches of the lagging leg are turned off at zcs and all switches of the cycloconverter circuit are commutated in the overlapping mode in the interval of zero voltage, which makes the circuit realize soft switching to the utmost extent and reliably solve the problem of peak voltage caused by the storing energy of leakage inductance of hf transformer
論文提出一種新型移相全橋軟開關周波變流型三相高頻鏈逆變器，電路的主要優點是：前級移相全橋的移相角控制在_ d _ i和_ （ overlap ） - _ d條件下，超前橋臂零電壓開通，滯后橋臂零電流關斷，並使周波變流器所有開關在零電壓期間重疊換相，使整機開關最大程度地實現了軟開關，並可靠解決了高頻變壓器漏感儲能引起的電壓尖峰問題。By using phase shifting control between right bridge leg and left bridge leg, the output cy cloconverter commutating while the bi - polarity three - state high frequency ac volage from the input cycloconveter is zero, . and commutation overlap of the output cycloconverter and polarity selection of the input voltage, the leakage inductance energy and the output filtering inductance current are naturally commutated, and zvs switching of the output cycloconverter are realized, the surge voltage and surge current of the output cycloconverters are overcome
通過輸入周波變換器右橋臂相對左橋臂的移相，讓輸出周波變換器功率開關在輸入周波變換器輸出的高頻交流電壓為零期間進行換流，並藉助輸出周波變換器換流重疊和輸入電壓極性選擇，從而實現了變壓器漏感能量和輸出濾波電感電流的自然換流、輸出周波變換器的zvs開關，解決了輸出周波變換器固有的電壓過沖和環流問題。
