Inhalt:
In this paper different approaches in precise measurement of gate voltages as well as drain-source voltages of modern SiC and GaN transistors are compared. An approach to calculate the necessary bandwidth of a voltage probe to reproduce the voltage slope is presented. Furthermore, state-ofthe- art voltage probes are compared in means of bandwidth, common mode reduction and response on EMI.
