摘要：
This paper analyses an off-nominal Class E ZVS amplifier, with an R.F. supply choke and the switch on-duty ratio D = 0.5, to identify conditions for its high-frequency and high-efficiency operation. Simple user-friendly analytical expressions for the essential parameters of the amplifier have been derived and subsequently validated by simulation and experimental results. It has been proven that the off-nominal amplifier can be optimized to outperform the nominal Class E amplifier with respect to crucial parameters such as, e.g., power efficiency or the operating frequency in some applications.
