Effective EMI Filter Design Method for Three-Phase Inverter Based Upon Software Noise Separation

Modelling, simulation and experimental verification for renewable agents connected to a distorted utility grid using a Real-Time Digital Simulation Platform

“…There are too many methodologies to design the appropriate EMI filter; some of them are based in trial an error. Novel methodologies are cited in several publications, including [30,31].…”

Adaptive-frequency Resonant Harmonic-Compensator structure for a 3-phase grid-connected photovoltaic system

“…In order to reduce the ripples created in the output currents of the inverter due to the high frequency commutation of the IGBTs, LC or LCL filter sections are needed [26,27]; meanwhile the electromagnetic interferences can be reduced by the EMI filters, whose design methodologies with trial and error method can be found in [28,29], whereas novel methodologies can be found in [29,30].…”

CM voltage compensation in AC/DC/AC interfaces for smart grids

“…A typical approach to conducted EMI reduction [17][18][19][20][21] bases on the application of the CM and DM filters that increase the impedance of the EMI current paths in conducted EMI frequency range. However, these solutions may bring about many side effects [9,12] such as creation of various resonant frequencies in system with uncontrolled paths for the passage of EMI currents generated in nearby circuits, lowering of the path damping factor due to introduction of additional series inductance, increasing of the EDM current amplitudes with lowered awaiting time to puncture Fig.…”
