对该放大器进行了精确的分析，给出了精确而简单的设计步骤，并给出了验证理论分析的实验结果。为了在任意开关占空比下实现最佳运行，确定了以下性能参数：电流和电压波形、集电极电流和集电极-发射极电压的峰值、输出功率、功率输出能力和负载网络的分量值。给出了几种开关占空比值下的输出谐波谱。对晶体管的功率损耗和集电极效率也进行了估计。采用BSX60 TO-39晶体管，在1 MHz频率下输出功率为3 W时，集电极效率超过95%。
Presents an exact analysis of that amplifier, an accurate and simple design procedure, and experimental results which confirm the theoretical analysis. The following performance parameters are determined for optimum operation with any switch duty ratio: the current and voltage waveforms, the peak values of collector current and collector-to-emitter voltage, the output power, the power-output capability, and the component values of the load network. The output harmonic spectrum is given for several values of switch duty ratio. The transistor power losses and collector efficiency are also estimated. The measured collector efficiency was over 95 percent with 3 W output power at 1 MHz, using a BSX60 TO-39 transistor.
