Electromagnetic Compatibility of Impedance Source Inverters

Krzysztof Bernacki, Zbigniew Rymarski

Abstract


In the last decade, many new structures of Impedance Source Networks have been presented and applied to a variety of powering systems. Electromagnetic Compatibility (EMC) testing is a required procedure, when introducing a new product to the market, in order to confirm that a particular device meets the required standards.

The novelty presented in this article are the results of research on the conducted disturbance and radiated emission on five selected Impedance Source Networks (ISN) structures that were performed in a certified EMC chamber along with a discussion of these results.

The description of the results will help designers to select the appropriate structure, and will help to determine the level of additional electromagnetic disturbances that can be expected by using the selected structure with respect to an inverter that does not use an impedance network structure. As yet, the research on radiated emission and conducted disturbances for Voltage Source Inverter (VSI) with ISN has neither been described nor analysed. The article concerns five Impedance Source Networks (ISN) structures.
