In power inverter applications
coupled to the mains a dedicated reactive filter
is unavoidable to interface the generator to the
power grid. This is necessary to fulfill the EMC
requirements of switched mode inverters, and
to ensure the required output characteristics
(current source). In this paper the output stage
of an inverter in conjunction with the matching
filter section and the power line model is
analyzed with respect to the influence of the
component parameters. The topology used
here leads to a structure of high system order
which was difficult to control and problematic to
model due to unknown varying mains and line
impedance behavior. To overcome the
resulting limitations of the low damped system
and to reach the goal of an always stable and
rouged system here a special compensator is
used. It is shown, that the optimal adaptation of
the presented structure leads to a simple,
insensitive, easy to use and very robust
solution. The presented concept is well suited
for mains coupled power inverters, especially
solar inverter applications.
