The widespread adoption of wideband semiconductor components such as SiC and GaN in photovoltaic inverters, motor drives, and automotive charging systems has driven the switching frequency and power density of three-phase inverters to unprecedented levels. However, this development has also brought with it severe measurement challenges: high voltages, intense electromagnetic interference, and the requirement for ultra-fast switching signal capture at the nanosecond scale
