Abstract: Leakage current and electromagnetic interference (EMI) are closely related to the common-mode (CM) circuit in transformerless photovoltaic inverter systems. However, the correlation between them is elusive, as they are always studied independently because of the different frequency bands involved.
Nevertheless, the direct connection of the PV sources to the grid through the power inverter gives rise to an important common mode (CM) current flowing in resonant circuits containing parasitic elements. This undesirable current can cause several issues such as electromagnetic interference (EMI) problem and safety difficulties [1, 2 ].

Power inverters produce common mode voltage (CMV) and common mode current (CMC) which cause high-frequency electromagnetic interference (EMI) noise, leakage currents in electrical drives application and grid-connected systems, which consequently drops the efficiency of the system considerably.
Abstract: Electromagnetic interference (EMI) filters are inevitable parts of power electronic systems. A novel EMI filter for single-phase grid-inverter is proposed in this study, to suppress the common-mode (CM) EMI noise. The noise source and propagation path impedances are analysed, and the interaction between AC and DC side is studied.
