Multi-phase power measurements are critical in applications such as multi-phase buck converters and three-phase power systems, including motor drives and inverters. While power analyzers are commonly employed in these settings, they typically provide a static view of the system, which may not capture the dynamic behavior of the signals involved. This presentation explores the advantages of using oscilloscopes for multi-phase power measurements, enabling a more comprehensive analysis of transient phenomena. Also reviewed is the fundamental principles of power measurements on oscilloscopes and the challenges posed by signal irregularities. A live demonstration illustrates the process of making a three-phase power measurement on a motor drive inverter output, showcasing how oscilloscopes can effectively capture and analyze dynamic states. Attendees will gain insights into leveraging oscilloscopes for enhanced power measurement techniques, ultimately improving their understanding of multi-phase systems and applications.
