OTP-Based Test System
Power electronics assemblies often cannot be tested using conventional technology for their electrical performance. Due to the adaptability of the instrumentation, the OTP concept offers an ideal platform even beyond the space requirements of several control cabinets. In order to achieve high test flexibility with different assemblies, the system was equipped with three-phase AC sources and AC loads as well as a precise three-phase power meter. DC sources and loads with different current and voltage ranges cover the test of frequent DUT operating parameters. Time-dependent voltage or current signals can be stimulated by an arbitrary generator with power amplifier. General measurements such as current, voltage, frequency, resistance can be carried out flexibly at various test points using the matrix concept. An oscilloscope with RF multiplexer is available for high-frequency measurements such as residual ripple, switching processes, etc.

Localized Electrochemical Impedance Spectroscopy
VS-LEIS
The VersaSTAT 3F applies an AC voltage to the sample emerged in electrolyte. This "global" voltage generates AC current to flow at the electrode / electrolyte interface. A dual-element probe is positioned in solution close to the surface of the sample. The electrometer measures a differential voltage measure between the two measurement elements as a measure of local voltage-drop in solution. This voltage-drop exists in solution because of current flow from local reactions at the sample, the resistance of the electrolyte and the spatial separation of the dual measurement elements.
