我们研究了一种效率高、结构简单可靠、频率可调范围宽的非线性电路。建立了在该电路中(交流和饱和状态运用)以铁氧体作为非线性电感的数学模型。从实验着手,借助于计算机辅助分析,探讨了该非线性电路的变频特性、倍频极限和功率输出。最后把计算机的计算结果与实验结果进行了比较。 We study a non-linear circuit with high efficiency, simple and reliable structure and wide frequency range. A mathematical model was established using ferrite as the nonlinear inductor in this circuit (AC and saturation conditions). Starting from the experiment, with the help of computer aided analysis, the frequency conversion characteristics, frequency multiplier and power output of the nonlinear circuit are discussed. Finally, the computer calculation results and experimental results were compared.
