Abstract

The paper deals with the general problem of EMI filters used for harmonic perturbations generated by the PWM converters. In particular - are presented the design aspects and experimental results for EMI filter connected between the active filter and the low voltage network. For a typical solution of three phase EMI filter, a FEM modeling of magnetic circuit is performed. For the designed filter, the measured transfer characteristics, both in differential and common mode are given. Are also presented the resistive and inductive drops on the load connected at one of the phases.
