1. 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(guān)周波變流型三相高頻鏈逆變器，電路的主要優(yōu)點(diǎn)是：前級(jí)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(guān)斷，并使周波變流器所有開關(guān)在零電壓期間重疊換相，使整機(jī)開關(guān)最大程度地實(shí)現(xiàn)了軟開關(guān)，并可靠解決了高頻變壓器漏感儲(chǔ)能引起的電壓尖峰問題。
2. It's difficult to find overlap mode in a sentence. 用overlap mode造句挺難的
