  • Abstract
    A generalized methodology of achieving class E versus quasi-resonant (QR) switching is introduced, and the associated resonant switch topologies are analyzed, with the conclusion that class E operation can be achieved for a given switching edge if the respective current or voltage is continuously differentiable (C1) through the switching instant. This concept is applied to show how the category of class E switches includes the QR switches, but contains a wider variety of configurations
