Abstract: The paper presents aspects for adoption of the automated test and measurement workflow and algorithms related to the study of power electronic converters. Particularly this is related with some peculiarities of various test bench configurations and how this test-bench configurations affect the speed, performance and accuracy of the carried measurements and produced data. First a test without a device is performed to evaluate the measurement instruments and after that the effect of it has been investigated. Then evaluation of the system is done with a converter in the loop, to investigate its' effect on the transient processes. The test is based on a virtual instrument (VI), written in Python programming language with various instrument control and data acquisition and processing libraries. The main idea of this VI is to preform efficiency tests of power converters. It is of critical aspect that the researcher is aware of this peculiarities in order to make accurate conclusions on power converter parameters such as efficiency, load and line regulation, reliability and safety of the devices tested.
