Abstract :
A class E amplifier with a clamped switch peak voltage with a Zener diode across the choke inductor is proposed and analyzed. Power loss in the Zener diode is reduced to 2/3 of that in the amplifier with a Zener diode across the switch. The effect of the Zener diode on the switch voltage waveform, output power, and efficiency are examined and experimentally verified.
