Abstract
Explicit expressions for steady-state behavior of the class E amplifier are derived. These equations are useful to predict the behavior of the class E amplifier outside the designed conditions. It is shown how the switch voltage and current waveforms change when duty cycle, frequency, or load resistance deviates from the designed values corresponding to zero-voltage switching/zero-derivative switching conditions. The theory was compared with PSpice simulation.
