In this paper, a novel 20MHz high performance DC/DC resonant converter is proposed, which owns well soft-switching characteristics, low voltage stress and small volume. With the significantly frequency improvement, the value and volume of passive components can be greatly reduced, contributing to a small volume. The detailed analytical derivation and optimal parameter design methodology of inverter stage, matching network and resonant rectifier stage are proposed in this paper. The soft-switching characteristics can be realized in a wide operating range. A 12V input, 5V/5W output prototype is proposed in the laboratory and the experimental results verify the feasibility of the proposed converter and design methodology.
