Abstract
Analysis of transient behavior is important for class power E amplifiers because high peak switch voltage imposed on the transistor during the transient response may destroy the transistor switch. However, transient behavior of class E amplifiers due to load variation has not been analyzed yet. In this paper, analytical expression for transient behavior of a class E amplifier due to load variations is derived using high-frequency and low-frequency circuit models. Derived transient behavior of peak switch voltage was experimentally verified with a 2 MHz class E amplifier. Experimental results achieved good agreement with the theory.
