Abstract
In this article, a novel 20-MHz high-frequency high-performance dc-dc resonant converter is analyzed, which owns the characteristics of soft-switching, low voltage stress, and small volume. The numerical analysis is conducted in time domain and the resonant parameters can be accurately calculated based on the corresponding expressions. A full resonant rectifier stage is adopted without using choke inductors, and the value and volume of inductors can be greatly reduced. A 12-V input, 5 V/5 W output prototype is proposed in the laboratory and the experimental results verify the feasibility of the proposed converter and numerical design methodology.
