Clamping of switch peak voltage with diode and transformer at output of class E amplifier

In this paper, a voltage clamp circuit consists of diode and transformer, which reduces the transient peak switch voltage of the class E amplifier with single dc power supply, is proposed. This clamp circuit clamps the output voltage of the class E amplifier when the amplitude of output voltage goes over the maximum permissible value. Simulation results showed that the proposed diode clamp circuit successfully reduces the transient peak switch voltage.
