This paper represents a highly efficient bidirectional full bridge GaN based DC-DC buck converter. The devices are used for their several advantages, such as size, weight, and efficiency over silicon device. The power devices allow to upsurges the switching frequency and also helps in attaining high efficiency. This enhanced speed of GaN device switching is employed to accomplish very improved conversion efficiency. In this article design considerations of different types of losses, converter design and applications of this converters is also highlighted. The efficiency measurements of power converter are tested at different frequency and 98% efficiency has been obtained. The converter has been simulated in MATLAB and the results are validated using “OPAL-RT.” Capitalizing on the potential of GaN technology, this DC-DC converter offers a significant step forward in achieving more sustainable and energy-efficient power conversion solutions.
