GaN's advantages over conventional semiconductors make it an excellent candidate for deployment in the transportation area. This work aims to develop a simple, one-sided DC/DC GaN-based buck converter for manufacturing and prove its feasibility through multiphysics optimization of the chosen topology. To enhance the design, the Ansys "Q3D tool" is employed to estimate parasitic elements, which are subsequently incorporated into an electrical model in the waveform viewer software "LTspice" to evaluate their impact on the switching node signal "Vsw" of the half bridge structure. Next, we will examine the overshoots and ringings by comparing the measured and simulated converter's Vsw and the output signals. We have implemented robust thermal management in this work. Additionally, this study provides an analysis of current density in the layout and heat distribution in the converter circuit. We will present more precise measurement results that align with the simulation in the primary outcomes, showcasing the effectiveness of the converter layout optimization topology.
