Abstract :
Analysis of transient behavior is important for class E amplifier because high peak switch voltage may be imposed to the transistor in the transient response. However, transient behavior of class E amplifier due to load variation was not analyzed yet. In this paper, transient behavior of a class E amplifier due to load variation is simulated with PSPICE. As a result, it is found that a high transient voltage is imposed to the transistor when low frequency load impedance suddenly changes to a higher value. Finally, a simple method to lower the peak transient voltage is proposed.
