  1. The key parts of barretter are made of irf840 field - effect transistor, the magnetic ring and high frequency choking coil which adopting negative temperature index. such components can provide barretters a wide applicable voltage 160v - 250v. low power consumption, minor temperature rise, stable functions, long life - span

    器核心元件採用irf840效應三極體,環及高頻扼圈採用負溫系數,這樣的元件選擇使整器適用電壓寬160v - 250v ,功耗低,溫升小,性能十穩定,確保其擁有很長的壽命。
  2. It is found from the experiment that under the conditions of peak magnetic field of 0. 57t, beam pulse fwhm ( full width of half maximum ) of 44ns, a microwave radiation pulse with fwhm 25ns and whole width of 35ns is produced, when the intensity of the guiding magnetic field rises, the peak microwave power changes little but the width of the pulse reduces. the a - k gap also has obvious influence on the microwave radiation, the stable and higher microwave output is obtained under suitable gap

    實驗中還發現,在峰值0 . 57t和束半高寬44ns情況下,得到了25ns半高寬和35ns底寬的微波脈沖信號,隨著導引增加,微波信號幅值基本不變,但國防科學技術大學研究生院學位論文是微波脈沖寬度會逐步減少;實驗中還發現線圈位置有一定的軸向調節,說明在軸向佈的一定變化內,器件都可以正常工作,這對以後的永系統導引的微波實驗有利。
  3. This paper studies on used the ac servo system based on ti dsp ( lf2407a ) and the foc and digital signal processing thorem, achieves following results : algorithm. we employ svpwm ( space voltage pwm ) algorithm, improve the efficiency of the electric source, and decrease the harmonious elements. we build the mathematic model of the system and simulate it on matlab platform, dsigne segmented pid regulator to adapt variable speed and widen the speed range. measurement. the velocity and electric current measuring, we adopt multi - sampling - rate and digital filter principles. as more improvements we make, the whole system gets a good results. pc control. the complete controlling system can be controlled remotely. so we develop the pc controlling program.

    採用定向脈寬調制演算法,提高了電源利用率,降低了逆變電壓的諧波,改善了電機的運行特性,降低了對電網的污染;在matlab平臺上建立了交同步伺服電機和電壓空間矢量脈寬調制控制系統的數學模型,在模擬的基礎上,對傳統pid調節器進行了改進,提出轉速調節器和電調節器採用段pid結構,根據給定轉速所處的區間,自動選擇相應pid調節器的參數,拓寬了調速,提高了控制精度。
