| 摘 要： | 在任意Q值和任意占空比D情况下对E类开关模调谐功率放大器进行了分析，根据谐振回路中电容值的大小，导出了放大器的工作方程，并用拉普拉斯方法，对放大器电路方程进行了求解。结果显示，当放大器的负载网络取不同参数值时，分别得到高Q值的正弦输出电压和低Q值的非正弦输出电压。在最佳工作条件下，给出了集电极电流和集电极——发射极电压波形。

| Abstract: | Class E switching-mode tuned power amplifier has been analyzed at any Q and any D in this paper. With the help of different capacitance in the resonant circuit, the basic equations governing the amplifiers operation are derived. Later the equations were solved in the Laplace transform method. The results showed that the sinusoidal output voltage at high Q and non-sinusoidal output voltage at low Q were obtained respectively when the parameters of the load network got various. The waveforms of the collector current and collector-emitter voltage are also determined under the optimum operation condition. |
