摘要
本文给出带有反向并联二极管E类调谐功率放大器的一般分析方法。文中首先讨论二极管导通角的确定,然后利用傅里叶分析与状态方程相结合的技术,推导出功率放大器响应的傅里叶级数表达式,并给出其性能参数分析,为该类放大器设计提供有效的支持。实际应用表明,本文提出的方法快速,可靠。
A general approach to analysis of class E tuned power amplifier with anti-parallel diode at switch is presented. First, the determination of diode active angle is discussed. Then the amplifier output response, along with performance evaluation, is derived and expressed in the closed form Fourier series by combining Fourier analysis and state equation technique. Applications to several amplifiers with varying param eters show that the method is fast and robust. The proposed approach affords an effective means to the exact analysis and design of class E tuned power amplifier with parallel diode at switch.
