Abstract :
This paper proposes filter design guideline for single-phase grid-connected PV inverters. By analyzing the instantaneous voltage applied on the filter inductor, the switching ripple current through the filter inductor is precisely calculated. Therefore, filter inductance can be designed accurately which guaranties the switching ripple current under the target value. Proposed filter design method is verified by experiment.
