Novel Digital Active Emi Filter Used In A Grid- Tied PV Microinverter Module

M.Ananthi, A. Arul, R. Ramesh

This paper presents the EMI reduction by the novel digital active technique used in a grid tied PV micro inverter module. The most commonly used passive EMI filter used for EMI mitigation in power converters comes at the expense of cost, size, weight power losses, and PCB real estate. DAEF is implemented with a grid tied photovoltaic micro inverter .the inverter stability is analyzed with the DAEF by the overall transfer function. The system compensation is designed based on the direct quadrant frame control technique
