  1. 1. nizn ferrite was developed for using in mini high frequency dc - dc converters and inductors. we measured and analysed the parameters of the nizn ferrite, which we concern about when designing the dc - dc converter. 2. the low loss sample of nizn ferrite were chosen for design - optimization of the high frequency transformer. based on the relevant theoretical researches, the loss properties of the magnetic core material and winding were analyzed in this thesis

    因此,以nizn功材料為開關電源芯材為基礎,並優化各種開關電源的設已成為國際上的熱點和技術瓶頸,本論文正是以上述背景為研究目標而開展工作的,主要進行的工作和創新有: 1 .對研製的新型高低功耗的功nizn材料進行參數的測試,並針對dc - dc變換器設關心的參數對芯材特性進行了分析,選擇在特定下,功耗較小的nizn材料磁芯樣品作為變壓器優化設的預備磁芯。
  2. It is presented that the theory and the manufacturing technology of such analog phase shifter, which are made from conventional 3db quadrature hybrids coupler with two identical varactor - diode networks to provide a shifted phase that varies continuously with biased dc voltage. several analog phase shifters have been made for different operating frequencies. each phase shifter has phase range more than 180, return loss better than - 20db, insertion loss 4. 8db including 3db attenuator, transmission difference less than0. 075 db. computer code phases. bas can present the referenced component values
