This paper presents the design of a resonant converter with a switching frequency in the very high frequency range (30-300MHz), a large step down ratio and low output power. This gives the designed converters specifications which are far from previous results. The class E inverter and rectifier have been selected for the prototype and the circuits are analyzed and simulated. Three different power stages are implemented based on different design parameters. The first prototype is with a switch with small capacitances, the second one is with a switch with low on resistance and the last one is with a large input inductor. The power stages are designed with the same specs and efficiencies from 60.7−82.9% are achieved.
