Power quality and electromagnetic interference (EMI) control are mandatory for any grid-connected power converter. This paper describes a procedure for LCL filter design in a grid-connected high power density converter (HPDC) with the objective to meet both power quality and EMI requirements. The performance of the LCL filter is simulated and then validated experimentally.
This paper evaluates different passive filter topologies of the grid-connected high power density converter (HPDC) for the purpose power quality control and electromagnetic interference (EMI) reduction. The harmonics generated by the switching circuits in the HPDC affect power quality at lower frequency as well as EMI at higher frequency. Various common passive filter topologies are carefully evaluated...
Using a flyback converter as a case study, an electromagnetic interference (EMI) simulation model including the non-linear behaviour of an isolation transformer is developed. To take into account the non-linearity of the transformer in the circuit simulation, the Jiles-Atherton (J-A) model that handles the non-linear behaviour of the magnetic core is proposed. As the non-linearity of the transformer...
