Abstract

The Gallium Nitride semiconductor technology allows switching operation at high frequency and supports voltage levels compatible with medium power applications. Its emergence has resulted in a number of works investigating the feasibility of high frequency DC/DC converter prototypes primarily in terms of efficiency. The present paper goes one step beyond and reports electromagnetic emission measurements, both conducted and radiated, made on a DC/DC converter operated at 50 MHz Very High Frequency, 30 V input voltage and 7.5 W power level. The measured performances are tentatively assessed to drive the design of future VHF converters.
