Previous analytical descriptions of the Class D-E resonant dc/dc converter using thinned-out method have been based on some assumptions, which are assumed to make it simple the evaluation about effects of thinned-out control on the equivalent impedance variation. Therefore the difference between the calculated values and the measured values is significant in case when thinned-out ratio is high. This paper presents a new analysis for this circuit. The equivalent impedance variation by thinned-out control is taken into consideration. The measured performance shows good agreement with the analytical performance in wide range.
