To improve power management systems in micro- and nanogrid applications, it is crucial to thoroughly evaluate the efficiency, output ripple, and operating frequency of DC-DC converters. This paper presents a detailed investigation of these critical parameters for custom laboratory-built DC-DC buck converters with Gallium Nitride (GaN) transistors. The study analyses and compares measurements to assess the converter's performance under varying load conditions. Efficiency is examined by varying input voltages and load levels to unveil the converter's operational boundaries. The investigation extends to the characterization of the output ripple. Furthermore, the impact of working frequency on both characteristics and design requirements is explored, providing insights into optimal frequency selection. A comparative analysis with industry-standard benchmarks underscores the converter's strengths and areas for improvement. This study not only contributes to the advancement of DC-DC converter design methodologies but also provides practical insights for enhancing power management efficiency in Smart Plug applications within micro- and nanogrid environments.

Abstract

To improve power management systems in micro- and nanogrid applications, it is crucial to thoroughly evaluate the efficiency, output ripple, and operating frequency of DC-DC converters. This paper presents a detailed investigation of these critical parameters for custom laboratory-built DC-DC buck converters with Gallium Nitride (GaN) transistors. The study analyses and compares measurements to assess the converter's performance under varying load conditions. Efficiency is examined by varying input voltages and load levels to unveil the converter's operational boundaries. The investigation extends to the characterization of the output ripple. Furthermore, the impact of working frequency on both characteristics and design requirements is explored, providing insights into optimal frequency selection. A comparative analysis with industry-standard benchmarks underscores the converter's strengths and areas for improvement. This study not only contributes to the advancement of DC-DC converter design methodologies but also provides practical insights for enhancing power management efficiency in Smart Plug applications within micro- and nanogrid environments.
