Abstract � Gallium Nitride and Silicon Carbide are two representative materials for the third generation wide bandgap semiconductor. Gallium Nitride power transistors have higher electron mobility than SiC, making them superior devices for high frequency and efficient switching. The lateral HEMT device structure is also a more suitable topology for power integration together with driver and control blocks to achieve a ultra-high power density module and system. This presentation will discuss an accurate and comprehensive evaluation of GaN switching characteristics. The effects of gate driver topologies, gate resistors and deadtime will be explored. Several different applications of high frequency GaN based power conversion will be illustrated.
