一種變頻電路的研究
INVESTIGATION OF A FREQUENCY CONVERSION CIRCUIT
-
摘要: 我們研究了一種效率高、結(jié)構(gòu)簡單可靠、頻率可調(diào)范圍寬的非線性電路。建立了在該電路中(交流和飽和狀態(tài)運(yùn)用)以鐵氧體作為非線性電感的數(shù)學(xué)模型。從實(shí)驗(yàn)著手,借助于計(jì)算機(jī)輔助分析,探討了該非線性電路的變頻特性、倍頻極限和功率輸出。最后把計(jì)算機(jī)的計(jì)算結(jié)果與實(shí)驗(yàn)結(jié)果進(jìn)行了比較。

Abstract: A nonlinear circuit is investigated, which is characterized by high effeciency, simple and reliable construction, and large tuning frequeney range. For the circuit operating in AC and saturation condition, a mathematical model of the ferrites as the nonlinear inductance element is built up. Along with the exp-erimental work done on the circuit, the frequency conversion characteristics of the nonlinear circuit, the limit of the frequency multiplication, and the power output are discussed by means of compute-aided analysis. Computed results by computer are compared with the experimental ones. -
