Abstract
In this paper a novel possibility to obtain dc-to-dc converters with high efficiency using GaAs MESFET switches is provided. A comparison with standard MOSFET is presented and solutions for reactive element, diode, and driver are proposed. Finally we give an experimental result for hybrid prototype 5V/10V-100MHz converter with an output power of 5W and a power efficiency of 76%.
