正向電流增益-
A novel parallel - serial type cttfc ( combined two - transistor forward converter ) with coupled inductor is present in this paper, and the performance of three parallel - serial type cttfcs is studied and compared. the performance of cttfc with coupled inductor is similar to the other two cttfcs while coupling coefficient is less than one and the converter working ccm ( continuous current mode ), and input - to - output voltage gain increase one times while coupling coefficient is one
本文提出了一種耦合電感並?串型雙管正激組合變換器，並對三種並?串型組合變換器的特性作了比較：耦合系數小於1且耦合線圈電流連續時，三種並?串型組合變換器特性相類似：耦合系數為1時，組合變換器輸入輸出電壓增益增大一倍。 -

The directional routing protocol ds _ dsr put forward by the author is the improvement of the current protocol dsr, complete routine discovery and maintenance by directional neighbor nodes routing table, source routing and directional steering. the research discovers the application of the directional antenna, compare the omnidirectional antenna can increases the networks " total throughput, obviously reduces the co _ channel interference ( cci ), multiple access interference ( mai ), enlarges the nodes " signal and interference to noise ratio ( sinr ), and because of the high gain of directional antenna can realize the communication with farther distance and less jump, end to end delay can decrease deeply, simultaneously, security of networks can be improved partially, the node energy also can be saved easily by power control
本文提出的定向路由協議ds _ dsr是基於對現有協議dsr的改進下實現的，通過定向鄰節點路由表、定向源路由和定向搜索來完成路由發現與維護。研究發現，定向天線的應用，相比全向天線可明顯提高網路的總的吞吐量，減少通道干擾、多址干擾，提高信干噪比，且由於定向天線的高增益可實現較遠距離、較少跳數的通信，減少了路由發現時間，這樣大大減小了傳輸時延，網路的整體性能得到了不同程度的提高，同時部分地解決安全問題，通過功率控制還可較容易的實現節能的目的。 -
