Abstract This paper discusses the DC side electromagnetic interference (EMI) filter design methodology for photovoltaic inverter System. It conducted an analysis of noise source and propagation path impedances of photovoltaic inverter system. A DC side filter design method is proposed based on the impedance mismatching between the EMI filter impedances and noise source/load impedances. And four different filter topologies are studied and compared. Simulation and experimental results give a firm support to the proposed method. Lastly, it discussed the experimental results comparing with the simulation results and verified the correctness of theoretical analysis.

Key words： Electromagnetic interference filter inverter
