Abstract
Electromagnetic interference (EMI) issue has
become one of the extremely important problems to be solved
in the photovoltaic (PV) inverter system. It is well known that
the static converters used in PV system are major sources of
conducted disturbances which are the common mode and
differential mode. Often, the solution used to reduce conducted
emissions consists to use the EMI filters. In this paper, a
complete computer aided procedure based on a co-simulation
Matlab and LT-Spice. A Database representing the parasitic
elements of the passive component, this last one allowed feed
the program of design of the filter under Matlab. Finally, the
final phase allowed to validate the filter performance with a
temporal solver or / and frequency under LT-Spice. Simulation
and experimental results give a firm support to the proposed
method.
