                Voltage-type sources such as storage battery, AC  grid and constant-output-voltage-regulated converters have  dominated as input sources for power electronic interfaces for a long time, leading to development of different power stages dedicated to voltage-type input sources. Recent penetration of renewable energy sources has initiated the use of current-type sources as well as input-voltage-regulated converters as input sources for power electronic interfaces. While the power electronic converter topology remains unchanged in both cases, steady-state and dynamic properties of the coupled source-converter system are quite different. Moreover, the voltage/current nature of the load contributes to the complex dynamics as well. The paper investigates the factors determining the dynamic properties of a power electronic converter in a specific arrangement. The findings show that the open-loop converter (without any internal or external feedbacks) automatically adapts its dynamic properties to the properties stipulated by source and load if certain terminal constraints are satisfied. If internal or external feedback is activated, the dynamic properties of the converter may be varied as desired; however, the control design process is substantially different for each source/load arrangement. The findings presented in this project have not been presented in the literature by far.
