Opis:: 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 are presented. The obtained results 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 can be observed at distant points under overhead MV lines. The compensation of the CM voltage sources on both the input and the output sides of the AC/DC/AC converter using proposed arrangement of compensators significantly reduces unwanted, EMC related, side effects accompanying the application of AC/DC/AC interfaces in Smart Grids.

Opis:: In this paper the method of the selection of dv/dt for EMI current ringing attenuation has been presented. The mechanism for the attenuation is first identified using the theoretical approach. It is shown that the attenuation occurs for rise time of the voltage equal to the inverse of the frequency of current ringing. The concept has been experimentally verified in DC chopper and frequency converter arrangements. The proposed method of ringing attenuation can be applied in power converters with flexible gate control and can be also utilized in a wide area of electronic circuits with a trapezoidal excitation for a signal integrity improvement.
