Loss Model For Gallium Nitride Dc-Dc Buck Converter, Rushi P. Patel
Loss Model For Gallium Nitride Dc-Dc Buck Converter, Rushi P. Patel
Pursuit - The Journal of Undergraduate Research at The University of Tennessee
In recent years, more research has been done on Enhancement Mode Gallium Nitride (eGaN) converters, as the world is moving towards more power efficient converters. Power converters play a major role in efficiently controlling and converting electric energy used by machines, systems, and everyday products. The process to make converters more efficient was complicated and slow in the twentieth century. One of the important aspects in power electronics is to evaluate different losses and minimize losses to achieve high efficiency of the converter. With help of simulation tools such as MATLAB and LTspice, this process has become much faster and …
Review And Characterization Of Gallium Nitride Power Devices, Edward Andrew Jones
Review And Characterization Of Gallium Nitride Power Devices, Edward Andrew Jones
Masters Theses
Gallium Nitride (GaN) power devices are an emerging technology that have only recently become available commercially. This new technology enables the design of converters at higher frequencies and efficiencies than those achievable with conventional Si devices. This thesis reviews the characteristics and commercial status of both vertical and lateral GaN power devices from the user perspective, providing the background necessary to understand the significance of these recent developments. Additionally, the challenges encountered in GaN-based converter design are considered, such as the consequences of faster switching on gate driver design and board layout. Other issues include the unique reverse conduction behavior, …

In recent years, more research has been done on Enhancement Mode Gallium Nitride (eGaN) converters as the world is moving towards more power efficient converters. The process to make converters more efficient was complicated and slow in the twentieth century. With help of simulation tools such as MATLAB and LTspice, this process has become much faster and reliable in the modern era. In order to make this process even faster, one of the important aspects in power electronics is to evaluate different losses in the converter. A model for estimating power losses for eGaN DC-DC buck converter (12V/1.2V) is illustrated …
