Extended analysis of idealized class-E operation with finite DC-feed inductance and preservation of zero volt switching at variable load

This work comprises an extended and comprehensive evaluation of idealized class-E operation with finite DC-feed inductance. It exhibits an analysis of varying switching duty cycle as well as varying switch voltage slope at switch-on time. As a result of this special cases for idealized class-E operation able to maintain efficient zero-volt switching while the load resistance changes is revealed which can be utilized for specific RF outphasing systems. Furthermore and as to the best knowledge of the authors we present the highest possible value that has ever been calculated for the power capability of idealized class-E operation namely 0.1092.
