Abstract

This presentation highlights the industry best practices for measurements on modern
power electronics devices such as SiC and GAN devices. These modern devices introduce new
complexities into power conversion circuits requiring the need for precise circuit timing and higher
sensitivity for gate threshold voltage and timing.
Common measurement pitfalls can be avoided by using differential and floating measurements and
understanding the link between CMRR and signal frequency. Today’s power designs can have
common mode voltages in excess of hundreds or even thousands of volts, while still needing to
measure small differential voltages, this common mode error can be even more severe. Wide
bandgap devices allow switching of higher frequencies, higher voltages and faster rise times, which
requires higher bandwidth scopes and probes with high CMRR. In this presentation, some solutions
for improving the measurement accuracy on SiC and GaN devices during switching will be
presented.
