The Infeasibility of a Zero-Current Switching Class E Amplifier
It has been shown that a class E amplifier may be configured to provide nearly 100-percent efficiency and zero-current or zero-voltage switching. A particular configuration, which supplies zero-current-switching when the transistor output capacitance is zero, is considered for the case when the transistor output capacitance is greater than zero. Equations for the switch voltage and current, the dc input voltage and current, the output voltage and current and powers are determined for the amplifier. The equations show that with this configuration, a zero-current-switching class E amplifier can not be physically realized. © 1990 IEEE
