Abstract

The authors describe the analysis of a more general class E amplifier configuration that can yield results for most of the other class E amplifier configurations published thus far by simply imposing the proper design conditions. The analysis takes into account most of the important parameters that affect the amplifier performance, such as the DC-feed inductance, the Q_L factor of the series-tuned circuit and the switching device ON resistance. Design and performance curves are given and discussed for the finite DC-feed inductance, shunt-capacitor, series-tuned configuration. It is seen that the amplifier performance is strongly affected by all of these parameters. Laboratory results show an excellent agreement between experimental values and theoretical predictions
