Optimal design of a class-E resonant driver

In many applications of class-E converters, custom made design of the isolation resonant network is impractical and off-shelf products are used. In this case, matching between the target output parameters and converter components requires an additional passive matching network that its parameters are found by a tedious optimization routine. This paper introduces a behavioral modeling based optimization method for class-E resonant converter, which significantly simplifies the component selection procedure. The method reduces the number of unknown variables during a simulation based parameter optimization search. The results of the optimization process are demonstrated on an off line, digitally controlled Class-E, PT based AC/DC converter.
