Presented in this paper are the results of research connected with common mode (CM) interference generated by ac/dc/dc power electronic interfaces, which will very probably be commonly used in the future vehicle-to-grid systems. The results obtained show that the conducted CM interference generated by these converters in a low-voltage grid can be coupled to a medium-voltage (MV) network and observed...
The idea of power electronic transformer is known already over 20 years. There are numerous papers written about power electronic transformers. In the literature one can find tens on different topologies, control methods, standards, requirements etc. It is easy to loose insight what topology to use and where. In this paper a general overview of the power electronic transformer technology in terms...
Presented in this paper are the specific conducted EMI related issues accompanying the application of Power Electronic Interfaces (PEI) in Smart Grids such as the flow of EMI currents in extensive circuits and aggregation of the interferences introduced. Compensation of the voltage interference sources inside of the converters has been recommended as suitable side effects mitigating technique.
In this paper the results of research connected with common mode (CM) interference generated by four-quadrant frequency converters and effective methods of CM voltage compensation will be presented. The results obtained show that conducted CM interference generated by these converters in a low voltage (LV) grid can be transferred by means of parasitic couplings into a medium voltage (MV) network and...
