Evaluation on filter topologies in high power density converter design for power quality and EMI control

摘要

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 in terms of reduction of total harmonic distortion (THD) and EML
