<Abstract>

This paper presents a frequency-modulation controlled resonant converter with the push-pull class-E inverter and the class-D rectifier. The Class-E inverter has no high-side switch in its topology, which is suitable to high-frequency operation. Additionally, it is possible to satisfy the ZVS condition in the entire ranges of the specified input-voltage and load variations by applying the class-E inverter. The ZVS region and output-voltage contours are illustrated on the parameter space, which are helpful for determine the component values. The validity of the design was confirmed by a quantitative agreements between the experimental results and the numerical predictions.
