DC Biased Impedance Measurements
by Florian Hämmerle - OMICRON Lab Several passive components used in power electronics applications exhibit non-linearities under DC bias.. These non-linear effects however, do normally not show up in small signal AC measurements. A possibility to reveal the non-linearities is to use a higher AC signal level or a DC bias offset. This offset can be a voltage or current offset. This talk focuses on the use of the Bode 100 and Bode 500 for DC biased measurements. Application examples and tips for practical test setups will be presented.
