Abstract—Thispaperpresentsthedesignofaresonantconverter with a switching frequency in the very high frequency range (30– 300 MHz), a large step down ratio (ten times), and low output power (1 W). Several different inverters and rectifiers are analyzed and compared. The class E inverter and rectifier are selected based on complexity and efficiency estimates. Three differentpowerstagesareimplemented;onewithalargeinputinductor, one with a switch with small capacitances, and one with a switch with low on-resistance. The power stages are designed with the samespecificationsandefficienciesfrom60.7–82.9%areachieved. Index Terms—DC-DC power conversion, inverters, rectifiers, resonant power conversion, switched mode power supplies, VHF circuits.
