Moreover, we give a further discussion on the numerical value calculation of temperature distribution. the main problem when we design the high duty - cycle high power laser diode array we face is the large amount of heat during its operation. so we change the proportion of some ingredients and the concentration of the dopage to gain high quality iii - v material
在激光器陣列的設計過程中，針對大功率激光器嚴重的產熱問題，尤其是高占空比工作時，會有更多的功率轉化為熱的現象，我們改進晶元材料的配比、摻雜，提出適應高占空比工作的器件版圖結構。 -
One is that the operation duty cycle can not be larger than 50 % because of the requirement for the transformer resetting. as a result, the voltage stress of the secondary diode is high, which limits the usage of dfc in high output voltage application
但由於變壓器磁芯復位的需要，其工作占空比必須小於50 ，從而造成占空比利用率不高，變壓器副邊電壓高，副邊高頻整流二極體的電壓應力大。 -
The clamping diodes conduct only once in a switching period, and the resonant inductance current is smaller in zero state, leading to a higher efficiency and reduced duty cycle loss. the operation principle of the improved converter and the comparison with the original converter are analyzed in this paper. the effect of the blocking capacitor in series with the transformer or resonant inductance is discussed, and a best scheme is determined
本文將諧振電感和變壓器交換位置，使變壓器與滯后橋臂相連，這樣箝位二極體在一個開關周期中只導通一次，同時零狀態時諧振電感電流較小，有利於提高變換效率和減小占空比丟失，本文分析改進后變換器的工作原理，並與改進前的變換器進行對比，討論隔直電容在不同位置對變換器工作的影響，確定一種最佳工程方案。 -
