How GaN-on-Si can Deliver Higher Efficiencies in Power Conversion and Power Management
This paper describes the benefits of gallium nitride on silicon (GaN-on-Si) technology in power designs. Key differences between silicon (Si), silicon carbide (SiC) and gallium nitride (GaN) technologies are discussed as well. The need for more efficient power conversion, including AC-DC, DC-AC and DC-DC, is present in every vertical industry where electronics is an enabling technology. This includes SMPS for telecommunications and servers, as well as mobile and wireless chargers and power supplies. In all of these applications the overarching requirement is greater efficiency and higher power density.
