  1. It also gives the motive of the ka - band vco and mixer, associated with the subject ' s requirement and the realistic conditions, according to which a proposal is confirmed that the gunn diode and the varactor are mounted in the same cavity to fulfill the vco and an antiparallel diode pair is used to fulfill the harmonic mixer. in chapter 2, based on the basic theory of negative resistance oscillating, we analyses the gunn oscillator and it ’ s tuning character. chapter 3 introduces the theory of millimeter - wave harmonic mixer

    以此為根據結課題需要和實驗室的實際條件,確定vco採用耿氏腔體振蕩形式,變容與耿氏安裝在同一個腔內以進一步減小體積,採用反向並聯二極體實現諧波;第二章介紹負阻振蕩理論及其調諧原理;第三章介紹毫米波諧波基本原理;第四章給出了振蕩及諧波的設計過程,整個組件聯調的結果;最後是結束語,分析了電路中存在的問題,指出了改進方向。
  2. Secondly, we present the set of nonlinear partial differential equations that describes the wave - particle interaction, by analyzing the output power spectrum, the limit cycle and chaotic oscillation of the radiation field in the traveling wave tube ( twt ) amplifier and the magnetically insulated transmission line oscillator ( milo ) are studied numerically, respectively

    接著,在論文的第三章和第四章我們從導出了一組用於描述場和電子相互作用的非線性偏微分耦方程組開始,利用譜分析法,以行波( twt )放大和磁絕緣傳輸線振蕩( milo )為例,數值研究了o型件和m型件中場的極限環振蕩和沌行為。
  3. According to the following design theory : the dsp calculates in real time and produces three phases spwm waves to control the on or off of the 6 igbts in ipm respectively. ipm then inverts the commutated single phase direct current ( insulated gate bipolar transistor ) into three phases alternating current. when modulated signals of spwm are changed, the on - off time of switches also changes, so as to the voltage and frequency of output signals

    本文提出了一種基於dsp (數字信號處理tms320f240 )的通用的三相間接變電源系統,利用分段同步調製法和查表法,實時計算不同率下的采樣周期、電壓幅值、輸出脈寬,產生雙極性spwm波形,經驅動放大後用于ipm ( intelligentpowermodule )中的絕緣柵雙極型晶體柵級驅動,以控制電源的輸出電壓和率,實現變電源的智能數字控制。
