Model verification and common mode current analysis of grid connected three
phase two level converters
Richard Haraldsson & Simon Lindvall
Abstract:
In grid connected power electronics where switching is used, harmonics are
created. High frequency currents are conducted through parasitic elements,
such as capacitive, resistive and inductive impedances to the chassi and
grid.
In this Masters thesis an in-depth model of a shunt active filter for high
frequency analysis is constructed. The purpose is to enable analysis of
higher frequency behavior reaching 1MHz. Using the high frequency model,
common mode currents can be simulated.
The model is built using high frequency impedance measurements of the
internal components in one of Comsys ABs active filters. Using the measured
component values and the measured parasitic elements a simulation model
could be designed.
This work has been carried out in collaboration with Comsys AB.
