Abstract
One of basic problems in a Class E amplifier operating at a high frequency is an appropriate drive circuit ensuring switch-mode operation of the amplifier transistor. The paper analyzes the influence of various methods of sine-wave driving on parameters of the Class E amplifier. Advantages and disadvantages of these methods are presented along with simulation data and experimental results for a 12W/500kHz laboratory model.
