Abstract :
The class E amplifier with a clamped switch peak voltage using a Zener diode is proposed and analyzed A higher output power is obtained when the maximum switch voltage is clamped. Design equations are derived for the output power and power losses. The effect of the Zener diode on the switch voltage waveform, output power, and efficiency are examined. The experimental verification is presented using a prototype circuit.
