“…Although other design and optimization techniques have been developed lately, based on a Spice circuit simulator and accurate device models for both the transistor and the inductors [Ramo04] [Gupt01], the presented state-space technique is more related to the theoretical Class E behavior. Furthermore, if all parasitic effects are taken into account and a strong nonlinear transistor model is used, the dependency of output power and efficiency on a certain parameter is not always clear.…”
